GENERAL NEWS ABOUT COMET HALE-BOPP 1995-O1 ---------------------------------------- John Pazmino NYSkies Astronomy Inc www.nyskies.org firstname.lastname@example.org 1995 September 1
Introduction ---------- This series of articles was written during the era of comet Hale- Bopp in 1955-1997. They show the build up of excitement as the comet strengthened and document some of the comet's record-smashing behavior. Because Hale-Bopp was so brilliant and showy, many astronomers accept that it may be the grandest comet they'll see in their lifetime. For sure as at mid 2009 there was no other comet that matched or rivaled it. The articles are collected here into one file under the date of the first of them. They were treated to minor editing.

POTENTIALLY BRILLIANT COMET, 1995 01 HALE-BOPP -------------------------------------------- 1995 September 1
[The information for this new comet comes from various Internet posts, including those from Mark Kaye, Gary Kronk, and Paul Schlyter. The ephemeris for 1995 was calcked by John Pazmino using Deep Space.]
Excitement is mounting over a slow moving 11th magnitude glow spotted in Sagittarius on 22 July 1995 by Alan Hale and Thomas Bopp, both using 40cm reflectors. We already have a pretty good idea of the path the object, comet 1995 01 (Hale-Bopp), will take as it enters the inner solar system in early 1997. The "O" is the letter, not the numeral. The big question is: How bright will it become? The answer depends a lot on whether the comet, still beyond Jupiter, is now undergoing an outburst that makes it much brighter than normally. Nevertheless, Brian Marsden announced on IAUC 6202, August 4th [of 1995], that this may become a spectacular comet for the northern hemisphere in late March and early April of 1997, as bright as magnitude -1.7! Marsden adds that several features of Hale-Bopp's orbit are reminiscent of the Great Comet of 1811, which remained visible for 17 months and sported two tails, one of which grew to 70 degrees long.
Discovery ------- After several months of no comet discoveries (one of the longest dry spells in recent years), on 24 July  Alan Hale (Cloudcroft NM) and Thomas Bopp (near Stanfield AZ) independently reported a new comet. The comet was discovered by Hale shortly after 11 PM local time on 22 July 1995 and was independently found by Bopp about a half hour later. The comet was then in Sagittarius not far from M70. It was diffuse, with some condensation, and about magnitude 10.5. Central Bureau for Astronomical Telegrams made the announcement on IAUC 6187 on 24 July. IAUC 6188 listed numerous precise positions that had been received from Australia and Japan after confirmation. A prediscovery image was announced on IAUC 6198. R McNaught of Anglo-Australian Observatory found the image on a plate exposed by C Cass on 22 April 1993[!]. The comet's total magnitude was then 18 and the coma was 0.4 arcmin across. The orbit given on IAUC 6198 indicates the comet was then 13.1 AU from the Sun
Observations ---------- Observations made during the first few days after discovery indicate the comet was magnitude 10.5 - 11. It had some condensation and possibly a short tail toward the north. The coma was about 1 or 2 arcmin in diameter. As at start of August various observers indicate the comet is magnitude 10.5, about 2 to 3 arcmin across, and weakly condensed. There is still a trace of a tail, or a slight elongation of the coma, towards the north. IAUC 6194 notes that CCD imaging by W Offutt (Cloudcroft NM) during 24-31 July seemed to indicate the coma was shrinking. It was also mentioned that Z Sekanina (JPL) examined the measurements Offutt obtained from his images and commented that the coma may be spiral shaped, similar to that shown by comet Schwassmann-Wachmann-1 when it undergoes an outburst. IAUC 6191 on 26 July gave the first orbit computation (listed as highly uncertain). Based on 57 positions obtained on 24-26 July, it indicated the comet would pass perihelion in early 1997! IAUC 6194 on 1 August gave a parabolic orbit based on 208 positions obtained during 24 July to 1 August. This new orbit, which is still considered "somewhat uncertain", had a perihelion date of 1 April 1997 and a perihelion distance of 0.9 AU. McNaught's prediscovery image was announced on IAUC 6198 and enabled Marsden to compute a very precise orbit. This new orbit indicated the general correctness of the orbit on IAUC 6194, except that the comet is moving in a long-period ellipse with a period of about 4,000 years, but the original orbit may have had a period of about 3,200 years. Marsden comments that comet Hale-Bopp "is not on its first pass from the Oort Cloud". The orbit from IAUC 6198, based on 248 positions, is as follows (equinox 2000.0); these are used in the ephemeris below:
Epoch=1995 October 10.0 TT Perih = 1997 April 1.3922 TT Eccen = 0.996348 Perih Dist = 0.916702 AU Arg of Perih = 130.4405 deg Asc Node = 282.4733 deg Incl = 88.8797 deg.
The comet's brightness trend is still a matter of question. The brightness in April 1993 is about 4 magnitudes fainter than the predicted magnitude based on the comet's currently accepted brightness model. Although this is a photographic magnitude and may run a little faint, this observation still offers additional evidence that the comet may be experiencing an outburst. It is, however, interesting that McNaught also announced that the comet was not visible on a plate exposed on 1 September 1991. The plates in question have normal magnitude limits of 21 and the predicted magnitude for the 1991 observation should have been only one magnitude less than that of the 1993 observation. The explanation might be that the comet was also undergoing an outburst at the time of the 1993 photograph. On the other hand, it could indicate that the current brightness model does not fit this comet and might need to be revised. Additional observations are needed before an accurate brightness model can be developed. An ephemeris for the remainder of 1995 appears below. It employs a somewhat more optimistic magnitude forecast, since it now appears that Hale-Bopp wasn't going through a temporary outburst when discovered.

IT'S COMING IN! ------------- 1996 August 1
Comet Hale-Bopp is coming in! Altho found over a year ago, it was a tiny dim smudge in Sagittarius until spring 1996. Now it's starting to flourish in our evening sky within easy binocular reach from the City. It moves slowly across the stars in Scutum, Serpens, and Ophiuchus all thruout the summer and fall. Hale-Bopp will leave us for a while in the winter when the Sun pulls it into his twilight glare. If you can right now spot M11, M13, or M15, examples of conspicuous DSOs, you'll have no problem with Hale-Bopp. Because of its slow motion you'll be able to follow Hale-Bopp across spells of cloudy weather. What a welcome relief from the mad dash of Hyakutake in this past spring! Binoculars show Hale-Bopp as a well-defined patch with a brighter center. Depending on the local sky clarity, you may notice an oval or wedge shape to it. While no or a small Moon is always best, Hale-Bopp is visible under a large Moon in a tempered form. You'll see just the condensed core like a misty star. The tail remains short over the months. The Comet is still far from the Sun and our perspective is more or less along its length. Do bear in mind that, like with Hyakutake, the length and pizazz of the tail is quite sensitive to your local sky conditions. The table was generated from Deep Space with the orbital elements of mid-March 1996 from JPL. The chart [omitted] was produced from the same elements with Earth Centered Universe. Both are moxied for the evening hours in New York. Only minor changes occur with newer orbital refinements.

MAGNITUDE ESTIMATION METHODS -------------------------- 1996 September 1
[Because of the comet fever in the AAA the question came up about assessing the brightness of a comet. A comet is a diffuse patch whereas the comparison stars are points. You are trying to gage one kind of visual target against an other kind. This is an age-old syndrome among astronomers: just look at the riotous variation in the cited brightness for deepsky objects! So I extracted thus this piece from the International Comet Quarterly website section on currently visible comets. It is a good summary of methods for assessing a comet's brightness, with some trivial spot editing.]
Some contributors are now starting to specify the magnitude estimation method that is used (this is not required, but is for observations submitted to The International Comet Quarterly). The goal of making a magnitude estimate is to obtain the total integrated brightness of the comet's head or coma. This is done by comparing defocused stars, of known brightness, to the comet. Specifically, the average surface brightness of the comet is compared with the surface brightness of defocused stars. Here is a quick summary of the different methods: The Sidgwick or In-Out Method: The in-focus comet is compared to the. out-of-focus comparison stars. It is very important that the defocused stars must be the same size as the comet. This is the most popular method and works very well for diffuse comets. Strongly condensed objects, such as C/1995 01 (Hale-Bopp), are more difficult to estimate using this method because it is very difficult to determine the comet's "average" surface brightness. The Bobrovnikoff or Out-Out Method: The comet and comparison stars are put out-of-focus together. Very easy to do. Works well for very strongly condensed objects. Can result in a significant underestimate of brightness in very diffuse and/or large comets. The Morris or Equal-Out Method: This method was developed to bridge the gap between the Sidgwick (works well for really diffuse comets) and Bobrovnikoff (best for strongly condensed comets) Methods. The comet is put slightly out-of-focus - just enough to "flatten" the brightness profile so that it is easier to determine the comet's average surface brightness. The average surface brightness of the comet is memorized as is its out-of-focus diameter. The comparison stars are then defocused to the comet's out-of-focus diameter (somewhat larger than its in-focus diameter). This.method is considered more difficult than the other two methods by some observers. Note that when the comet is very condensed, this method "becomes" the Bobrovnikoff Method and when the comet is very diffuse, it becomes the Sidgwick Method. Thus, the other two methods are subsets of this method. There are other methods, most notably the Beyer or Way-Out Method, but the ones given above are the methods recommended for making magnitude estimates today. Each method requires practice, particularly when comparison stars are not in the comet's field.

UPDATED COMMENTS ON THE 1993 OBSERVATION OF C/1995 01 (HALE-BOPP) --------------------------------------------------------------- 1997 January 1
[Dr Brian Marsden, CBAT, posted this statement on his website on 24 October 1996. For a wider distribution to the paper-based world, he let EYEPIECE reprint it here. It relates to a prediscovery image of Comet Hale-Bopp from 1993.]
Since late 1995 there have been suggestions in the Internet stating that the 1993 Apr. 27 prediscovery image (cf. IAUC 619B) of this comet is "not correct", with orbit solutions indicating it to be in error by as much as 30 arcsec. When the image was first noticed, by R. H. McNaught on a plate taken with the U.K. Schmidt, it was some 9 arcmin from the preliminary ephemeris then available (1995 Aug. 1). It should be also noted that McNaught's reexamination in late 1995 showed his measurement to be good to well within 1 arcsec. Furthermore, his measurement of the trail of the faster-moving minor planet (3343) on the same plate demonstrated that the exposure was correctly timed. As I surmised long ago, the problem with fitting the comet's orbit is quite clearly that, if one tried a standard orbit solution, the sheer weight of the 1995 data would throw a large residual into the single 1993 position, basically on account of the systematic errors in the GSC reference-star system used for most of the measurements. After all, the many hundred 1995 observations covered only a small part of the sky. By substantially reducing (e.g., by a factor of ten) the relative weight of the 1995 data, it was in fact possible to fit the 1993 position completely satisfactorily. The alternative of invoking the effects of nongravitational forces on the comet seemed very unlikely at the comet's large heliocentric distance, even if one believed, as some did, that the comet's great activity involved enormous relative mass loss in terms of vaporizing carbon monoxide. If the surmise were correct, it would presumably be found that the fit to the 1993 Apr. 27 observation would again improve as the comet's observed arc extended, with the observations during 1996, though continuing to be numerous, covering a greater area of sky. This did in fact happen, acceptable orbital solutions being possible quite early in the year with the relative weight of the current data reduced to only a factor of five. since then there has been further steady improvement. Finally, the latest orbit solution, given on MPC 28052, utilizing 1385 observations extending to 1996 Oct. 16, is fully able to incorporate the 1993 observation with unit weight:

The (O-C) of the 1993 observation is -1.2 arcsec in R.A. and -0.4 arcsec in Decl. Actually, the point has been reached where it really ~ does not matter whether the 1993 observation is included or not. The outcome is almost precisely the same whether considered in terms of the orbital elements and their formal errors or in terms of the near- perihelic sky position, which is now formally predictable to better than 1 arcsec. Statements to the effect that occultations by the comet's nucleus can be predicted more accurately using orbital solutions that omit the 1993 observation are thus patently false. This is not to say that occultations near the time of perihelion can yet be precisely predicted. Sources of error are the small nuclear size, the star catalogues used and nongravitational forces in the cometary motion. The first of these will require last-minute relative measurements of comet nucleus and star to be occulted to better than 0.05 arcsec. In the absence of such measurements, star-catalogue errors are likely to result in near-perihelic unpredictability to some arcseconds. The possible effects of nongravitational forces are unknown, and they proved to be a severe problem in predicting the post-perihelic position of comet C/1996 B2 (Hyakutake), for example. While both comets are clearly very active, one might surmise that the larger relative size of C/1995 01 (Hale-Bopp) will result in little nongravitational influence on this comet's motion. As noted on IAUC 6287, the last perihelion passage of C/1995 01 occurred close to 4200 years ago. In the absence of nongravitational forces near perihelion, the next return after 1997 will be some 2380 years hence.

IT'S FLYING DOWN THE WIRE! ------------------------ 1997 February 1
Comet Hale-Bopp, 1995-01, is heading onward toward the Sun virtually on schedule and within prediction. Despite some temporary trepidation in brightness last year, Hale-Bopp is already a mean comet hitting magnitude 3 in early January 1997. While mid northern observers lost it during conjunction with the Sun, arctic countries with their round-the-clock night followed it all along. By readtime it'll be prominent in the predawn sky even from the city. Who will turn in the first sighting from anywhere within the five boros? From Manhattan? From below 59th Street? From Times Square? From ... [snip]. The chart here [omited] gives the track thru the stars at 05:00 New York time -- NOT at Oh UT -- as a representative hour for viewing. It was prepared from Deep Space from the orbit elements listed below. Hale-Bopp is a binocular sight in Aquila, Sagitta, Vulpecula, and Cygnus. In darker skies or with sharper vision, it should be seen by naked eye. The trick is to first see Altair and Deneb. These two stars anchor the path in the sky. Altair is 15 degrees above the horizon pretty due east in mid February at 05:00; Deneb, 30 degrees, northeast. They may be blocked by skyline or horizon shmutz. Your chances improve steadily during February for two reasons. The Sun moves away from this region, lifting it into the early morning darkness. Hale-Bopp brightens to 2nd magnitude by end January, 1-1/2 by mid February, 1 by end February. Assuming all goes well we got a big bright beautiful comet in the morning sky as February closes. The tail, too, will lengthen both from intrinsic growth and our more sideways perspective of it. The chart shows a nominal size based on a 1/10 AU (15 million kilometer) true length. If you fix to photograph the comet, start practicing now! So many readers were saddened by Hyakutake because they didn't prepare for any picture-taking. You better get out and polish your star photography skills, particularly in the winter night. And, please!, get your film developed right away so you can compare the results with your field notes! Film and processing are truly very cheap education. Being that you'll be looking in predawn, with dark-adapted eyes, with most local lights shut off, under clear [and cold] winter skies, there's a chance you'll catch a glimpse of the 'summer' Milky Way. If you do, let us know! Give the usual dissa & datta. For those with comet-plotting programs, the elements, tweaked for 12 January 1997, are:
peri date = 1997 April 1.13427 peri AU = 0.9141138 excentric = 0.9950938 inclinat = 89.42956 deg asc node = 282.47088 deg arg peri = 130.58980 deg
The crossover into the evening sky for us in the City is about March lOth when Hale-Bopp moves into Cepheus. It'll then be low in the northwest shining at magnitude zero! And then ... .

THE HALE-BOPP COMET IS STUPENDOUS! -------~------------------------ 1997 May 1
I had to give up on summarizing the reports of comet Hale-Bopp from our readers simply due to the sheer number of reports! I got notes about the comet mostly via email and -- surprise! -- mostly from comet-watchers not affiliated with the Association. Why? EYEPIECE and the Association are quite well regarded far beyond our cozy praecinct in the city. The one lament everyone had when giving a report was about the weather. The entire country was hit by contrary weather, either allnight clouds or clouds surrounding the comet-viewing hour. Some people report trying for many days -- or weeks! -- before finally getting a clear sight. So, what I have here are the names, dates, and places of the observers listed chronologicly. Yes, a lot of you folk buttonholed me at our meetings to recount your views. But everything blends together and I can not separate who saw what from where at when. Please, if you want to be in our list, do come back to me. I'll get uou in the continuation of this table next month. Once a person spotted Hale-Bopp, he generally followed it regularly thereafter. In the table I indicate such a person by 'all Mar' or 'all Apr' in place of logging in each report from that person. Oh, one other thing. Please deliberately state in the body of your report the actual date, hour, and observing site. Do NOT count on these being noted correctly in the email header or signature. Merely saying, "I went out yesterday from work and saw the comet ..." is too loose. Try, "I went out on March 17th, 6:00PM, from work in Jackmanville, Missouri, and saw the comet ...". OK? Thanks!

THE HALE-BOPP COMET DAZZLES THE WORLD ----------------------------------- 1997 June 1
I continue my list of Hale-Bopp reports still flooding into EYEPIECE from all over the world.. Like for the list last month the accounts are sent In mostly by email from observers not yet affiliated with the Association. There were a bunch of reports I had to toss for the idiotic. omission of some crucial fact. Like the placename of the viewing site. Or the explicit date and hour of viewing. Or -- no kidding! -- the identify.of the very observer. Please, never assume the header or signature will correctly disclose the proper site, date, and name. Put them deliberately in the text. The weather still is a chronic source of complaint. Many of you saw the comet on one occasion and then were blocked off of any further views for days and weeks by clouds! Yet others toughed it out thru haze, mist, skyglow, cold (it's still winter in northern Great Lakes and Canada). We're getting delirious sightinqs from the southern hemisphere. After the many long months listening to northern stories and ogling northern imagery, the south folk are absolutely wild about this comet. Yes, there are a flock of catchup listings here. A lot of you got hold of me at our various meetings and blurted out a story. But in the din around me I lost.track of who saw what and where and when. Thanks for telling me again in calmer moments! Now to answer a frequent question. 'all Mar', 'all Feb', &c do not mean the comet was observed on all or even most days in the month. It means that sightings were made repeatedly in the month. This notation I use to collect multiple sightings in a month into one entry. Uh, ummm, what happened to the actual stories themselves? We got them all safe and sound. Should I post them on the Association's web site at www.aaa.org? [By 2009 these reports may be lost.]

That's it for now. But the reports keep rolling into EYEPIECE right up thru presstime! I'll post them in next month's lIst. And if this comet remains within naked-eye range until New Year's of 1998 I'll have to continue this column for a while. But, hey!, you may never, like never, see an other comet like Hale-Bopp for the rest of you life. Just go to sleep tonight with that thought, OK?

HALE-BOPP STILL GOING STRONG -------------------------- 1997 July 1
I continue the listing of Hale-Bopp reports and fill in the catchup ones, too. Hale-Bopp is sliding into the twilight glow in the southern hemisphere by late Hay and early June. Hence. the influx of reports sort of 'shut off'. Don't worry. This comet is coming back into our morning sky in the fall.
