General news
    June is the first of each year's two 'sea-change' of astronomy 
activity. Events running on a school-year schedule go into recess 
while summertime events start up. In Sep-Oct the change-over reverses. 
I some times have the case of an event having no session in May, being 
in the '???' section, and still having no instance for June. I follow 
that event's pattern from prior years, usually placing it in the 'S/O' 
    World Science Festival runs into June 2018, ending with a 
science street fair in Washington Sq on the 3rd. NYSkies works with 
the Festival on Saturday the 2nd at Pier 1, Brooklyn Bridge Park. We 
are astronomy resource crew to distribute star & planet charts, point 
out the stars, handle astronomy questions. Event features a science 
lecture, starviewing, and music/dance, all starting at 7PM. Event 
could be called off for adverse weather. 
    Alley Pond Enviro Ctr notes that its monthly astronomy nights 
include an indoor talk. The event is weather independent. NYC Events 
previously listed it as 'clearsky starviewing, cancelled for clouds'. 
    The 'Jews in space' exhibit at VIVO Instt continues to late June 
2018, from intense public interest. There is also an extra lecture 
honoring israel's first astronaut Ilan Ramon on June 21. 
    Our Seminar on June 1 is one day after the May Manhattanhenge 
window. We will step outside to watch the Sun set a bit off of the 
line of 14th St. The Seminar on July 6 is a couple days too early, but 
we'll again watch an off-centered sunset. 
    In 2018 the United Nations staged several public events on a wide 
range of subjects. None so far were astro/sci. With reconstruction at 
the UN winding down, some offices found that events opened to 
outsiders as a UN effort to alleviate construction nuisance, improved 
public awareness of their work. They on their own  continue to offer 
events to the public, now without the targeted invites, like the ones 
I sporadicly got over the past several years. You do have to register 
and sometimes pick up a visitors pass to enter the campus. Almost all 
are short-notice events, missing the upcoming NYC Events. Events of 
potential interest for NYSkiers will be posted in our Yahoogroup and 
email list. Please mind well that the topic could be thoroly 
repulsive, even tho it is considered worthy of UN attention. 
    Montauk Obsy has three events in June 2018 at different locations 
hours and locations. See under June 15, 27, 29. 

City News 
    Amat Obsrs Soc on 18 May 2018 called off its 'City of stars'  tour  
for 19 May for impending rain. Rain date is June 2nd. The 19th was 
rainy, shifting between thin drizzle and strong downpour.  
    At the NYSkies Seminar on 18 May 2018 Steve Kaye described his 
recent trip to St Louis MO. While there he visited Cahokia, remains of 
a preColumbian  society just across the Missouri Rv in Collinsville 
IL. He examined Woodhenge, in replica because the original wood 
structure long ago decayed. He showed, with handouts of an article, 
that the inhabitants used it to keep track of seasons and lunar 
motion, similar to Stonehenge. 
    World Science Festival in April-May 2018 found that unauthorized 
outfits were soliciting as the Festival. NYSkies received a couple, 
requests, which we handed over to the Festival for investigation. 
Festival advises that supporters work only with its official agents. 
    NYSkies Astronomy Seminar on 4 May 2018 explored the planets 
Jupiter and Saturn, now coming into the nightfall sky. We also 
refreshed our mind for Mars, topic of a few sessions ago. Mars is 
still an owl-hour object but increasingly under watch by observers. 
Jupiter slided east one more zodiac constellation since 2017, then in 
Virgo, now in Libra. He takes one year per constellation to fill out 
his 12-year circuit thru the zodiac. Saturn dwells in Sagittarius, 
taking for about 2-1/2 years in each constellation to complete his 29-
year round of the zodiac. For the next several years we'll discuss 
Jupiter and Saturn together in one session. here to gore we treated 
the two in separate sessions. The planets are now closing together 
toward a major conjunction in 2020. Such meetups come at 20-year 
intervals, the last few in 2000, 1980, and 1960. Yes, I saw ALL THREE 
of them! Mars, Jupiter, Saturn are in or approaching their 
oppositions. They go thru retrograde loops. Those for Jupiter and 
Saturn are sways to-fro more than 'loops', like that coming up for 
Mars in June. We saw that the progress of all of the planets is best 
monitored with binoculars, since many of the stars around them are 
dim. The loops invite photography, specially in a series a week apart. 
Unlike mars,  Jupiter and Saturn stay about the same brightness all 
the time. They do get dimmer near solar conjunction, but then they are 
in twilight with few background stars. In contrast, Mars is steadily 
on the increase, to surpass Saturn and then Jupiter by late July. The 
wide range of brightness for Mars comes from the 5-to-1 range of his 
angular diameter from opposition to superior conjunction. Jupiter as a 
telescope target is always a delight. In the smaller scopes his moons 
dance around him. Larger scopes reveal the cloud bands and the Great 
Red Spot. The GRS waxes and wanes in prominence yearly and also drifts 
in longitude around the planet.. Planetarium software that simulate 
close-up views of the planets usually use a stock map of clouds but 
then need an addiurnate longitude fo the GRS. This is taken from a 
current Jupiter observing source, like an astronomy magazine or web. 
The software then plots a reddish spot at the proper longitude for the 
GRS. Jupiter illustrates the flip-flop in orientation for astronomy 
pictures, now with north at top. Traditionally south was at top 
because early telescopes had as few optical surfaces as possible, 
maximizing the thruput of photons,. such scopes yielded 'up-side-down' 
images, south up for northern observers. Modern scopes with clearer 
lens material and image capture can produce views in any orientation. 
The GRS is in Jupiter's south hemisphere, being near the top of older 
pictures and near the bottom in modern ones. The moons orbit in 
Jupiter's equator plane, which is close to the ecliptic. The moons 
swing around Jupiter fro side to side rather than 'going around' him. 
Jupiter sources publish charts of the moons displacement east/west of 
the ball and tables of events among them. These include eclipses, 
transits, occultations against the ball.. Before 1970 the moons were 
numbered,I-IV. To promote spaceprobe visits to Jupiter, NASA revived 
proper names assigned by Marius, never in common use: Io, Europa, 
Ganymmede, Callisto. None of Jupiter's other 60ish moons are visible 
in home telescopes. Saturn presents a beautiful scene more or less 
static for each apparition. His rings are still wide open, starting to 
close up since maximum phase in 2017. The north face is tilted to us 
now. We saw how tough it was to properly interpret crude scope views 
of Saturn in the 1600s. Galileo drew Saturn as a triple planet, 
assuming the ring ansae were companion spheres. Huygens in mid-1600s 
sussed out the annular nature, showing that the rings are fixed in 
space and we see them fro different asides during Saturn's motion 
around the Sun. We learned that the last edge-on phase, when the rings 
disappeared in small scopes, was in 2009. The previous maximum south-
side phase ws in 2002,. Then maximum north-side open was in 2017, next 
edge-on in 2024. Some of us wondered if the colors shown in modern 
pictures of Jupiter and Saturn are real because most times they see 
the planets in small scopes as 'black-&-white' or in a single weak 
tint. In some telescopes of the 1970-1990 period, colors were muted by 
suboptmal design and build, a situation that dissuaded planetary 
observing for a long while. Modern scopes do give good color 
rendition. Some observers inspect the planets in twilight. Colors 
stand out without the glare and contrast of a dark sky background. Of 
Saturn's moons, five or six are within reach of home scopes. Titan, 
the largest moon, is always in sight, altho it can be missed as a 
field star. The others require careful skill and a detail chart for 
the day and hour of viewing. The moons run concentric with the rings, 
going around Saturn, making it all the harder to identify them. We 
noted that the rings are a plane of separate rocks and boulders, 
individual moonlets. This was suggested in the mid 1800s and confirmed 
in the early 1900s A solid ring could never be stable, keeping 
centered on the ball, and would tear apart under tidal and centrifugal  
forces across its width. The rings are lettered A,  outer, and B, 
inner, separated by Cassini's division. The Crepe ring, ring C, is 
sometimes seen as a shading on the inner edge of ring B. We finished 
the session with a look at the just-issued picture of the Milky Way by 
the Gaia project. It was compiled from the craft's survey of 1.7 
billion stars. A large picture in the takeaway showed the the all-sky 
scene of our Milky Way in full color. We'll study this again at the 
next session. Takeaways were maps of Jupiter and Saturn paths in sky, 
close-up views of both planets, sample tables of Jupiter moon 
positions and events, example early drawings of Saturn, Huygens's 
diagram of the tilted rings, general array of Saturn moons, angular 
extent of Jupiter moons if all were somehow visible to eye or 
binoculars, views of Saturn at several oppositions. 
    On 10 May 2018 NYSkiers helped fill ISAW's lecture hall to hear 
about Islamic science penetration into Europe in the 15th-17th 
centuries. The appreciation of astronomy, mathematics, medicine was 
demonstrated, in spite of political and military hostility against the 
Arab infiltration into europe. 
    NYSkies Astronomy Seminar on 18 May 2018 walked thru the backdoor 
from blackholes to Einstein relativity. I gave a slideshow on 
blackholes, the backdoor to relativity, to Amateur Observers Society 
in April. The audience lost way because there were no takeaways and it 
couldn't keep track of the maths from the slides on screen. This 
present Seminar was a major upgrade with the maths in takeaways and a 
healthy dialog among the astronomers. Every one seemed to be heading 
in the path toward personal pursuit of relativity, banking off of 
their familiarity with blackholes. Explanations of blackholes are 
reasonably mature and most home astronomers do understand how 
blackholes work. We recalled that descriptions for home astronomers of 
relativity, special and general, often are so shallow that the subject 
seems too complex to understand. We saw that te main difficulty with 
relativity was that its effects and phaenomena are so small with few 
convincing examples to illustrate them. A blackhole is the extreme 
case of general relativity whose behavior is dramaticly different from 
that experienced  far from the blackhole. Without realizing, a home 
astronomer is comparing a regime of spacetime in a strong gravity 
field with that in his own, safe, weak field. We began with a review 
of Newton's laws of motion and gravity. We saw immediately that Newton 
ran into the concept of a blackhole! His inverse-square law and 
replacement of a bulk mass by a point mass produce a runaway growth of 
gravity field strength with proximity to the point mass. This is in 
essence the blackhole. Newton avoided this situation by asserting that 
all real bodies have a surface o block too-close proximity to the 
central point, keeping a finite gravity field strength. Newton also 
had problems with 'mass'. He used it as the property of matter to 
resist change of motion and also as the property that generates a 
gravity field. The two are distinct features of matter, yet they 
seemed to be measured by the one parameter 'mass'. Newton by experiment 
found as best he could the two were identical. Until the late 20th 
century we weren't sure why 'mass' stands for both gravity and 
inertia. We didn't know at the meeting what the newly-found Higgs 
boson tells us. Nothing more was done until Michell in late 1700s 
proposed that the largest stars in space could not be seen because 
their escape velocity is greater than lightspeed. The worked with 
imperfect numerical values but came up with a star's maximum radius is 
500 times the Sun's, assuming the same density. He worked with 
Newton's formula for the combination of mass and radius until it 
 made the escape velocity equal to lightspeed. He also note that the 
presence of such a 'dark star' is revealed if luminous, visible, 
bodies orbiting it. We reminded that some blackholes today are studied 
by monitoring their orbiting stars. Today we usually hold the mass 
constant and let the radius shrink. When it reduces to a value that 
makes escape speed equal lightspeed, we have the blackhole. For the 
Sun this radius is 2.9km (almost always rounded to 3km); Earth, 9mm. 
This limiting radius was first worked out from Einstein's theory by 
Schwarzschild in 1910s and is the Schwarzschild radius. So far we were 
going over much familiar territory, with most members adding their 
comments into the discussion. We next slided over to relativity, 
starting from the formula for escape velocity. First we transposed it 
to get o a statement of energy in a gravity field. A body when dropped 
from a given distance from the attrahent loses potential energy, which 
is converted into kinetic energy. We noted that the energy equation 
applies to other forms of energy, not only mechanical.. The goal now 
was to derive, in a backdoor method, the relativity connection of time 
or space between observers in two gravity fields. The blackhole model 
makes this easy because one observer is near the 'event horizon' while 
the other, Earth, is a safe distance away. We chose to work with the 
unit of time, rather than of length, called dT. To get to this unit, 
we needed an energy that is simple, yet contains dT. We picked the 
energy of a photon, given by E=h*f, h being Planck's constant. Because 
eventually this h will drop out of our formulae, we have E::f, 
E::1/dT. We wrote out the equations for energy near the blackhole and 
in ideally a zero gravity field. For all known blackholes we are so 
far away the gravity is zero. The result is that the perceived dT by 
the sage observer is related to that of the close-in observer by the 
ratio of observers's distances from the blackhole.  The safe observer 
perceives the close-om observer's dT as larger,  greater. Time seems 
slower to the safe person than for the close observer. In the limit as 
the close-in person approaches the event horizon, his time experienced 
at the safe observer stops, dT ->infy. His activity is 'frozen'. 
Blackholes were at first called 'frozen stars'. 'Blackhole' was 
initially treated as a naughty word, specially in Europe. By the 1980s 
it was in routine use, often as one word. We skipped a similar 
derivation for special relativity due to accidental omission of a page 
in the takeaway. We slided into special relativity ny applying logic.  
By comparing the relative speed between the two observers and 
lightspeed, the standing person perceives time at the moving person as 
slower. dT is greater. We noted carefully that in special relativity 
each person can be the 'standing' person and the effects at the 
opposite person are reciprocal. In general relativity thee is no 
symmetry of effect. Each person is actually in a different gravity 
field. We saw that 'time' is not just the reading on a clock, as in 
silly cartoons of space travellers seeing a wall clock running slow. 
Time applies to ANY AND ALL activity: heart beat, metabolism,, metal 
rust, wood rot. All these procede at a normal pace for the person 
attached to them but are perceived to run slower ny the other  
observer. Altho this Seminar was among the more mathematical ones, 
most members felt they were now better prepared to appreciate 
Einstein's theory of relativity, at least for comparing unit time 
between observers. Takeaways were the printed slides from the April 
    At the Seminar on 18 May 2018 we examined a full-color print of 
Gaia's new portrait of the Milky Way. It was issued in late April in a 
news piece from the Gaia office. We saw that toward the galactic 
center stars are mostly yellow. Around the anticenter stars are mostly 
blue. A couple astronomers explained that the center the older yellow 
supergiants. The spiral arms away from the center have younger blue 
supergiants. We mused that digital imaging of the MW in summer and 
winter may being out this same color distinction, but I have not heard 
of such attempts. 
    NYSkiers got a triple-whammy of shows about nuclear energy in May 
2018! On the 20th they heard what happened at the Ukraine's Chernobyl 
station. The lecture was at the Ukrainian Museum. On the 21st they 
explored how atomic powered submarines work, explained by a nuclear 
engineer from China. The talk was at the Pfizer Bldg. At National Grid 
HQ on the 24th they saw how a tsunami destroyed Japan's Fukushima 
power plant. All three shows were short-notice events missing May's 
NYC Events but posted in our Yahoogroup. 

Sky News
    May 2018 opened with a does of raw summer weather! Temps rose to 
the 30Cs with humid air and little breeze. Relief came on the 3rd in 
evening with a thunderstorm that grazed the City. It threw down wind-
blown rain and stirred up cool breeze. Storm passed south of NYC with 
typical thunder, lightning, heavy rain. 
    Overall May 2018 was a poor month for observing. We had a couple 
clear nights but most nights served up cloud or rain. Temps ranged 
from mild to full summer heat. 
    he omega Centauri hunt was a bomb-out in April-May 2018. The sky 
was never dark and clear enough to try for the globular cluster. I'll 
put up the challenge again in April 2019 for an other go at it. 
    No night in May 2018 was close to a potential Milky Way night. The 
window for possibly spotting the MW continues thru June 30. 
    Violent thunderstorm sweeped over NYSkies on 2018 May 15 mid 
afternoon thru night. It hit NYC and LI with heavy rain, but Metro-
North and New Jersey suffered felled trees, ripped-up power lines, and 
coastal flooding. Rail service in M-N was delayed by trees falling 
into tracks. Some roads and rails closed from storm debris blockage. 
    During thunderstorm of 2018 May 15 at least three tornados were 
touched down in NYSkies. One scored ground thru Orange & Sullivan 
county, NY. Other two were hit & run events in Putnam county, NY. All 
three were weak with central winds of up to 200KPH. No reported 
injuries, deaths, major structural damage. 
    Jupiter at nightfall moves into center south in June, followed by 
Saturn and mars in midnight-owl hours. The three are in their 
retrograde loops all summer: 
    event        | Mars   | Jupiter| Saturn 
    west station | Jun 26 | Mar  9 | Apr 18 
    opposition   | Jul 27 | May  9 | Jun 27 
    east station | Aug 27 | Jul 10 | Sep  6 

    The 'ring flash' may be seen at Saturn's opposition on June 27, 
2018, but it demands continuous inspection of the planet for a couple 
weeks before and after opposition. It can not be obvious with only a 
look at opposition or with only sporadic views around hen.  The planet 
spikes in brightness, a few tenths magnitude, because at opposition 
the ring moonlets completely hide their shadows behind them. The 
entire ring surface is lighted. It may be best to take digital 
pictures of the planet in the sky repeatedly and asses the brightness 
against nearby stars.  This phaenomenon is a subtile one, often missed 
by experienced observers, even me.
