General News 
 ----------
    I thank NYSkiers Myrna Coffino and Gregory Homatas for posting 
under-known new activities around town. At first i copied them into 
our Yahoogroup until I found they already so that. In some cases their 
tips leaded to new members of NYC Events. 
    Many events during September were knocked out by repeated local 
flooding. Rounds of heavy rain overflowed rivers, swamped storm 
drains,  overwhelmed runoff fields. They caused widespread ruin in 
cellars, to vehicles, farms. In some cases rain over NYSkies fell 8-10

    We welcome new member american institute of Archaeology to NYC 
Events. It has seasonal lectures on ancient peoples and cultures. The 
talks commonly feature satellite imaging, remote sensing, geodesy, 
cartography. It meets in various places on Manhattan.
    Lamont-Doherty Open House on 13 Oct 2018 may attract LOTS of 
NYSkiers! It on 27 Sep 2018 advised NYSkies that it has FREE PUBLIC 
busses to and from the Open House. They are the regular Columbia U 
campus buses that leave from Teachers College, 120 St & Broadway. 
Service begins at 09;15 EDST, then every 15 minutes. Here to fore the 
bus was treated as internal Columbia service. Some NYSkiers used to 
get a ride by hanging cool and mixing with Columbia riders. 
    We also welcome New York Map Society to NYC Events. It meets at 
Woe World School, Madison Sq MH, or the Main Branch of NY Publ Liby. 
 The org looks after maps, mapmakng, cartography, geography. it meets 
    Morris Museum Astro Soc now seems to meet every month on 2nd 
Thursdays. It previously skipped Jan, Feb, Jul, Aug. 
    The United Nations General Assembly session continues to oct 6. By 
end September the gridlock around the UN is relaxed with transit and 
traffic more or less back to normal. Be specially careful to follow 
instructions for any UN public events during the GA meetings because 
there could be tighter security and detours within the campus. 
    qWestport Astro Soc has two lectures in October. The regular on e 
ison the 16th; the 20th highlights viewing the Moon. 
    Simons Foundation opened its 2018 lecture season on Sep 12 while the 
steam explosion crater smoldered under its windows. The hole covers 
two of 5th Av's four lanes, squeezing traffic thru the repair zone for 
a couple blocks.  The enclosing wall was taken down, leaving waist-
high fences to look into the crater. 
    College of SI observatory is still closed since early 2018. It then 
was damaged by winter weather with repairs pending. I moved it to the 
'???' section. 
    AstrO Soc of Toms River Area is active but its webpage for events 
still seems empty. It remains in the '???' section. Please inquire at contact for club 
activities.

    Cortlandt St station, South Ferry line, opened early on 8 Sep 2018, 
not the originally planned early october. It fits into the former 
station's envelope with more entries and new underpass between the two 
lateral platforms. it has a plain, almost bare finish, with 'World 
Trade Center' name tablets and chilled-air vents. Name tablets on 
columns are 'WTC-Cortlandt' because the station is engulfed by WTC m 
the uptown fare control area has overlooks to watch people walking 
under the station. As at now there is no transfer to other lines, like 
Cortlandt St, Montague line, or Fulton Center. 
    The 'secret subway shuttle' along Central Pk w is REAL! It's a NYC 
Transit bus signed up as 'to subway', stopping only at stations along 
the 8th Av line from Columbus Cr to 110 St. Certain stations are 
closed for rebuild and the bus moves riders to other open stations. It 
issues a special ticket to allow transfer to the subway since the 
regular bus ticket is only for bus-bus transfer. There seems to be ONE 
vehicle on the 4km route Because the bus duplicates the frequent M10 
route, that continues farther downtown, the shuttle has few riders. 
    There was an all-day public conference at the UN on 26 September 
2018, smack in the middle of the lockdown of Midtown Manhattan for the 
General Assembly meeting! I missed it for busyness at my office and 
it's close to issue date of this NYC Events. Any reports from NYSkiers 
at the conference will be noted in November's NYC Events. 
    The Village Voice newspaper waved farewell on 2018 August 31. It 
was the first alt-culture paper in US, starting up in  1955 to cover 
news and 'advice' for the Village lifestyle. In this century it fell 
on hard times, first offering it free on Manhattan, then free for all 
points. It shrank in size, dropped major columns, lost ads.  It 
reduced to a thin paper similar to others set out in pull-boxes on 
street corners. In April 2017 is ended print publication, turning only 
online presence. 
    NYSkies Astronomy Seminar on 2018 September 7 discussed blackholes 
in the Milky way galaxy, leaving out those in other galaxies. The 
topic was prompted by high interest in blackholes from recent news 
about the Milky way's central blackhole. We traced the history of 
blackhole as a theory or maths model before wW II. The BH effect was 
first worked out by Schwarzschild right after Einstein released his 
general relativity. It remained a maths exercise until the late 1930s 
when astrophysics hinted that a supernova could collapse so strongly 
to crush its core into a blackhole. In the 1960s with newly fielded 
astrophysics satellites we found X-ray hotspots along the Milky way 
belt and concentrated toward the galactic center. Most were recognized 
as blackholes in a binary star system. The BH was accreting gas the 
from the visible companion and causing it to radiate   the energy X-
ray energy profile matched the theory and models of a BH. because 
these BHs are the remanents of supernovae, they are called stellar 
BHs.  The first stellar BH  confirmed is Cygnus-X1, orbiting a 9th-
magnitude star in Cygnus. The star is quite half between beta and 
gamma Cygni, 1/2 deg NE of eta. In the 1980s-1990s we found BHs at the 
center of certain other galaxies with masses of hundreds of millions 
or billions of Suns, but none yet was seen in the Milky Way. In late 
1990a qw suspected a BH for the Milky Way be noticing certain stars in 
apparent orbit around an empty point, Being that the galactic center 
is visually blocked the observations were made in infrared and radio 
bands. Certain of these wavelengths penetrate the obscuring dust. In 
2008 the BH was confirmed when we actually tracked one star over a 
complete lap of its orbit. The BH is small, only about 4 million 
Suns..A passing gas cloud, G2, in 2014 came close to the BH, possibly 
to be ripped to shreds by its gravity. It survived a;tho badly 
distorted. In May 2018 one of the orbiting stars, S2, rounded its 
pericentron with hope that the gravity would cause observable Einstein 
effects. There is no standard word for the periapsis of a BH orbit, 
pericentron is a general one for 'vicinity of the center'. It did show 
obvious redshift in its spectrum due to both tangential and 
gravitational effects, amounting to a fictitious excess speed of about 
200KPS.We explained the nature of 'event horizon' as a distance away 
when escape speed equals lightspeed. it is not a 'ground' or 'barrier' 
that a falling object crashes into. It keeps falling toward the BH 
point, with ever increasing speed and adds its mass, spin, electric 
charge to the BH. we noted that for all home astronomy functions, and 
to a very close approximation for the Milky Way BH, we played with the 
Schwatzschild model. We forgo attempts to build in spin or electric 
charge. The Milky Way BH and star S2 handed home astronomers a 
wonderful exercise in both Newton and Einstein physics. Many of the 
results presented by campus astronomers an be replicated with only 
high school maths. Spawned by the high interest in the s2 events, I 
composed an article about it, with the maths worked out, at 

    www.nyskies.org/articles/pazmino/mwbh.htm

Takeaways were historical articles on BHs, graph of newton's missed 
chance to discover BHs, maps of the Milky Way, early plots of  X-ray 
sources, mechanics of binary BHs, pictures of stars orbiting Milky Way 
BH, graphs of star S2 orbit and redshifts, abstract of high school  
science fair project to find more BHs in Milky Way. 
    Dr Neil Tyson, Hayden Planetarium, starred on PBS 'Firing line' on 
15 September 2018. He discussed the declining state of general and 
science education in the US and railed against those who bend science 
to support a political principle. He also stressed that one of the 
greatest opportunities for human advancement is exploration of outer 
space,m with benefits flowing to all peoples. Tyson emphasized he is 
not into politics and does not ally with particular leaders or 
parties. 
    Brooklyn College in early September 2018 abruptly closed the 
Brooklyn Center for Performing Arts on its campus. The theater, in 
whitman Hall, was under rebuild to open in fall 2018 but was delayed 
indefinitely. College fired all staff  with a few assigned to part-
time duties. Center was a major space for concerts, conferences, 
plays, and outside rental and also a 'rainy day' site for shoes at 
nearby open-air Midwood field. 
    NYSkies Astronomy Seminar on 21 September 2018 examined the minor 
planets of the solar system, the asteroid or planetoids. We learned 
that Kepler thought something was peculiar about the spacing of planet 
orbits in about 1600, altho he was a Copernicus advocate.tThere was 
'too big' a space between Mars and Jupiter, a factor used against the 
Copernicus model. We traced the work of Titius and Bode, who in mid 
1700s worked up a geometric sequence closely matching the planet orbit 
sizes. With Earth as unity, we saw a 'hole' in the series for 2.7 with 
no planet. When Uranus was found it fitted into the series, sparking a 
hunt for the 'missing' planet. We learned that vonZach in 1780s looked 
for the planet with no luck. In 1800 a new hunt by a coalition of 
Europe observatories bagged asteroid Ceres in 1801. We learned Ceres 
was lost after only a few days, feared gone for good. Gauss invented a 
new orbit calculation method to recover Cers in 1802. Three more 
asteroids, the term proposed by Herschel, were found by 1806. We call 
these the 'charter asteroids: Ceres, Pallas, Juno, Vesta, followed 
regularly be home astronomers in small scopes. No more wre discovered, 
in spite of repeated searches, until the 1840s. then after asteroids 
were found in almost every year thru the 1880s. Wolf applied 
photography to asteroid hunts and the number of asteroids rose to 
about 500 in 1900. We learned that many asteroids were discovered by 
accident as streak on pictures taken for other purposes, spoiling the 
image. Asteroids were numbered in order of discovery and the finder 
gave it a name. Because the first bunch were named for female mythical 
figures, the practice continues today. At first the name, if not 
feminine, was converted to feminine form, but later ones were left 
alone and declared grammaticly feminine. We saw the number of asteroid 
swell so rapidly that orbit computations couldn't keep in a pace. We 
walked thru the designation of a new asteroid, first given a discovery 
name. This is the year of discovery, a letter for the half-month 
(skipping I and Z), and a serial order letter (using all 26 letters). 
By the 1980s we ran out of letters, finding more than 26 asteroid in a 
half-month, and rolled over to a second and more rounds of the 
alphabet. A final number in the designation tells how many alphabet 
rounds were completed before the instant one. As example we parsed 
'1999-AN10'. This was found in 1999, 1st half January, 13th in instant 
alphabet, 10 full alphabets completed.We figured out that this was the 
273rd asteroid discovered in early January 2018. After an orbit is 
worked up a sequence number, continuing the historical sequence, is 
assigned and the discoverer may award it a name. In the 1990sm partly 
as a spinoff of patrols for ICBMs after the Soviet Union collapsed, 
automated electronic searches starting raking in thousands of 
asteroids. In the early 1990s we had only 4,500 asteroids on record. 
By the late 1990s we had around 20,000. In mid 2000s the count passed 
100,000. Today we have a full one million asteroids, and counting.  
Until the 19980s almost all asteroids orbited the Sun in the Asteroid 
Belt, a ring 2 to 4 AU radius. We knew a few with orbits so dmall or 
excentric they did cross or bruised Earth's orbit, such as Apollo, 
Amor, Apohele, and Aten. We group asteroids by orbit characteristic, 
named for a prototype. An Apollo  asteroid is one whose orbit 
resembles that of asteroid Apollo. We treated asteroids before the 
Space Age simply as rocks that either broke up from a former planet or 
never coalesced into one. We studied photos of asteroids, and comets,  
visited by spacecraft to see their varied surface,  shape, size. We 
traced a development parallel to  the ICBM program, assessing damage 
from nuclear warfare. After the Cold War and the discovery of several 
small asteroid coming near to Earth, this work shifted to tracking 
asteroid threats. We learned that several asteroids actually did hit 
Earth in this century, l;ike over Russia, sudan,  and Botswana. They 
were 'asteroids' because when found they were given asteroid 
designations, only to watch them crash into the Earth a few hours 
later. We learned there is no official division between asteroid and 
meteroid, the rcok in space before becoming a meteor. The two are 
really the same kind of object except for size. We compared pictures 
of asteroids for size, ranging from a few hundred kilometers to less 
than one. When as asteroid comes within about 1/4 Au of Earth we can 
examine it by radar to reveal surface texture, shape, companion 
satellites, rotation. Takeaways were diagrams of asteroid orbits for 
several groups, disposition along zodiac, paths in sky,several strange 
asteroid orbits, plots of orbit  mutations, simulation of asteroid 
collision, examples of historical asteroid craters on Earth. 
    I and Michelle Girard attended an educator workshop at Intrepid 
Museum on 22 September 2018. We took breakfast under, litterally!,  
the Shuttle Enterprise with serving counters wrapped around the Soyuz 
capsule. We heard talks on duplicating the Antarctic journey of 
Shackleton and NASA efforts to get public schools to promote science, 
specially for young ladies. She and I split to see concurrent features 
of the workshop and explore the Intrepid. I took a guided tour of 
Intrepid's space exhibits, built several science toys from household 
items, made a [somewhat] working model of ISS robot hand. 
    A vagrant set fire to the parking garage of Kings Plaza mall, 
Kings Pz BK, on 2018 Sep 17 ~08:50 EDST. He was caught on security 
film and arrested. Fire totaled ~130 new Mercedes cars on 2nd floor 
from several Brooklyn car dealers, who rent the space to store some of 
their stock. Arsonist claimed the cars were hang-outs for sex  and 
wanted to burn them out. The mall's stores and roof-top customer cars 
were not harmed but some 17 people in garage were injured. Both ground 
and marine firefighters put out the 7-alarm blaze.

    September was almost a total loss for observing. Just about every 
night was cloudy, rainy, foggy. Many days were humid and torrid, temps 
in the low 30Cs. Only the last week of September  was actually cool 
autumn air, but still with rain or cloud. There was no chance of 
catching any Milky Way from the City. The MW viewing season continues 
thru end November. 
    Comet observers lost the close flyby of 21P/Giacobini-Zinner in 
early September 2018 from rain, cloud, fog. The comet came into 
binocular range in Camelopardalis --near THAT star cluster! -- then 
travelled roughly along the Milky Way thru Auriga, Gemini, Monoceros. 
It faded and moved into morning twilight.
    NYSkies starts its annual Globe at Night campaign in October. 
Orion enters the nightfall sky near end month, for convenient 
inspection. Use the charts and instructions in our web

but the dates are not yet moved moved up for this year. it is 
imperative that you gain dark adaption before assessing sky 
transparency, else you get severely depressed readings.
    The Tribute in Light beams were totally smothered in cloud and  
fog on 11 Sep 2018. They were only a weak vertical glow. As I measured 
at 22:30 EDST,  the beams ended only 7-1/2km up before they blended 
into the surrounding cloud. 
    Jupiter and Venus close their evening apparitions in October.  
Saturn is sliding into evening twilight. Mars is fading and shrinking, 
now resuming direct movement thru Capricornus. The sky in Sep 2018 was 
never clear enough to assess  by eye the status of the mars dust 
storm. His color was filtered by mist or thin cloud. 
    Uranus and neptune are in high sky in early night. Neptune 
requires a telescope while Uranus can be followed in binoculars. Cut a 
finder chart, with their paths, to pick out the planets from 
surrounding stars. 
    Just after sunrise on 22 Sep 2018 the Sun sprouted a solar pillar 
6-7 deg tall. It was tinted yellow and partly obstructed by morning 
cloud and mist. The Sun himself was a yellow glowball thru the clouds. 
    On 24 Sep 2018 a weak parhelion dextrum floated between roving 
clouds in early to mid morning. It was easily mistaken for a bit of 
cloud, a soft white patch. It  apparently faded away by 10h EDST.
