General news
 ----------
    Please note in the monthly calendar the first Friday in July, the 
5th, is NOT flagged as a Seminar night. This day is within the 
Independence Day period. We shifted the first meeting of July to the 
12th. This happens to be at the end of the July Manhattanhenge season. 
We'll step outside to watch it, with caution for the possible new 
traffic flows in 14th St. 
    A general caution for events requiring GI photo ID. Some are more 
strict about the ID offered. Some driver licences, a common ID, are 
sprcificly marked 'not valid for federal identification' or similar, 
which some event sponsors interpret to mean it is not a government ID. 
More events are rejecting building, business, school IDs. I see  
occasional people tuned away at door for a too weak ID, altho none so 
far as a NYSkier. 
    Hayden Plm had a series of lectures since April but I learned of 
them only in late May. I list the remaining ones, June 3 & 25.  
    Mid Hudson Astro Assn skips meeting in June. its next session is 
in July. 
    Intrepid Museum revised its summer programs, no longer having 
periodic astronomy nights and astro cafe' Intrepid is panning for July 
several events for the 50th anniversary of Apollo-11. 

City News
 -------
    NYC DEM starts in June installing large sandbags along Large 
Manhattan waterfront, like those  low-lying shores else where in City. 
Bags are rectangular boxes 120cm high in irregular rows to hold off 
flooding in future storms. 
   On May 15 NYC Mayor deBlasio launched his president campaign. The 
official debut was on the 16th at Good Morning America TV show.  
Thousands of spectators outside the street-level studio boosted him 
with slogans and chants. Later in day Prez Trump tweeted welcome and 
good luck to deBlasio. deBlasio will exploit his achievements as mayor 
to beat 20+ contestants for Democrat nomination 
   The new OMNY tap-&-go fare payment starts on May 31  on Staten Is 
buses and central section of Lexingron Av subway. It was under test by 
transit workers since April. Until OMNY is fully in place you still 
need MetroCard. In initial phase, OMNY handles only pay-per-ride 
fares, not unlimited or discount fares available thru MC. Also, a 
transfer mark put on MC does not carry over to an OMNY card or 
personal payment device, and vice versa. If you pay fare with one 
medium and 'transfer' via the other, you pay two separate fares. All 
OMNY farepoints will keep MC slots until conversion is complete in 
about 2022, them MetroCard is retired from service. 
    Utilities in Long Island and Metro North sectors of NYSkies in 
spring suspended new or expanded piped gas service. NYS officials are 
no longer allowing new pipelines in state to increase supplies. 
Customers now with gas service and new ones taking over exiting 
service keep their service but may not expand it. Customers taking up 
or building premises with no gas service may not obtain piped gas. 
    NYSkies Astronomy Seminar on 3 May explored the blackhole in 
galaxy M87, with its new image. This session is a do-over from april 
19, when many NYSkiers took care of Passover-Easter duties. We walked 
the story of blackhole concepts from Newton's gravity crisis in the 
1600s. He saw that when an attrahent body is replaced by a point mass, 
the gravity field near it increases without limit. He discovered what 
nature was supposed to always prevent, the singularity. His solution 
was to assert that celestial bodies have solid surfaces to stop too-
close approach to the point mass. In the 1780s Michell worked out that 
a star could be so massive that its escape velocity excedes 
lightspeed. Light could not leave the star and we could not see it. He 
showed that the star could be revealed by small bodies orbiting it. We 
saw how in Einstein's theory of relativity the blackhole event could 
occur. Schwarzschild showed that around a blackhole there is a radius 
where the escape speed equals lightspeed.In the 1930s Oppenheimer 
found that a star could collapse into a blackhole. Astrophysical 
models and observation. We saw charts made by astrophysics satellite 
of x-ray and gamma-ray sources that required relativity theory to 
investigate. The sources were probably real blackholes formed by 
collapsed stars. The term  'black hole' for these objects was coined 
by Wheeler in the 1960s and is now commonly 'collapsed' into one word. 
We then looked at blackholes in galaxy cores. The first one we found 
was in galaxy M87. We examined pictures of early views of this 
blackhole before its nature was known. We discussed interferometry 
networks of radio telescopes, leading to the Event Horizon Telescope 
project. It captured the blackhole image thru its extreme angular 
resolution of microarcseconds and wavelengths to penetrate intervening 
gas/dust. The picture shows the inner accretion disc at the edge of 
the closest stable orbit for matter. The empty dark blackhole itself 
nests on this disc. We saw just how big this blackhole is compared to 
the solar system.. We learned that the wavelength received, 1.3mm, is 
stretched from the emitted wavelength by the strong time dilation. The 
swirling motion of the gas is also slowed by this dilation. By good 
luck M87 is in high sky during the spring. We can spot its location in 
Virgo. Some of us observe M87 as a deepsky target and can show it thru 
our scopes. Takeaways were diagrams of Newton's problem, historical 
articles on blackholes, diagrams of blackhole structure. map of the 
Event Horizon project sites, illustration of building the blackhole 
image, size comparison of M87 blackhole and solar system, skymap for 
spring with M87, photo of Virgo galaxy cluster with M87. 
    Colin Davey on may 20 19h EDST discussed and signed his new book 
at Shakespeare & Co bookstore, Upper West Side MH. It, 'The American 
Museum of Natural History and how it ot that way', traces the 
construction of the present Museum, now comprising a dozen buildings 
accumulated of its 150-year life. Refreshments were served and book 
was at sale. Davey on May 22 was guest on NPR, when he highlighted 
assorted historical curiosities of the Museum. 
    On May 20 17:00  EDST a pro-Israel rally was staged at 7 Av & 48 
St, Times Sq MH. attracting ~1000 fans, it condemned antics of 
congressioners Ocasio-Cortez,O mar, Talib against Jews and Israel. 
Rally featured several pro-Israel speakers and a billboard truck 
displaying video/audio of Omar's statements.  It circulated thru Times 
Sq streets during the show. Opposite side of 7 Av had anti-Israel 
rally of about 100 fans. Both groups were peaceful with no reported 
police interventions. 
    On May 1 ~17:30 EDST single-prop plane ran into low-visibility 
weather and probable engine trouble. It trailed a 'GEICO' ad banner, 
heading to base in Somerset NJ. It dropped the banner into lower New 
York Bay and landed in soccer field at Miller Field, New Dorp SI. 
Female soccer team in practice cleared off of field safely for plane. 
Pilot was not harmed and NYPD and US FAA are investigating incident. 
    NYSkies Astronomy Seminar on Friday 17 May discussed 
Manhattanhenge. We first watched a slideshow, an improved version from 
last year, on the history and astronomy of Manhattanhenge. By some 
mishap the projector displayed the show in mirror image, with all text 
flipped right-left. We let it alone and used the takeaways that had 
the pictures right way round. We learned how the Manhattanhenge sunset 
effect occurs along Manhattan gridiron streets. We learned how the 
gridiron was established, a spinoff of the American Revolution. We saw 
scenes of New York from the early 1800s with wide open sky and low 
buildings. The Sun was in sight over most of its daily arc. We studied 
the annual displacement of the sunset, and sunrise, points as the Sun 
travels thru the zodiac.  When the azimuth of sunset matches the 
azimuth of the street we have the Manhattanhenge effect. We saw New 
York then just manhattan Is, grew in the 19th century into the new 
street grid. The City was a low four-story town due to effort to climb 
stairs to high floors and pressure in the water system. The City grew 
northward rapidly, way more than the estimated kilometer/century to 
reach 42nd St by the 1850s. Yet the cityscape still allowed a view of 
the Sun over his entire daily arc. A sunset along a street had no 
special meaning. We saw hoe in the 1880s several engineering and 
technical developments changed the cityscape. Steel framework 
construction replaced masonry. this made possible taller buildings 
with large rentable floors. Elevators relieved the work to walk up to 
higher floors. subways and buses were laid out to bring people to the 
new tall buildings, each occupied by thousands of workers. We saw the 
cityscape grow into streets hemmed in by towers. The Sun ws blocked 
for most of the day. He was visible only when he shined in the line of 
a street. At sunset he shined on the horizon between towers. The scene 
reminds us of the alignment of sunset, or sunrise, with the stone 
pillars at Stonehenge. This effect was originally an internal event 
for us astronomers, who occasionally gathered in small groups on 
certain streets to watch the sunset. in 2002 Natural History magazine 
had article by Dr Tyson, Hayden Planetarium, on astronomy features in 
new York, with the Stonehenge sunset effect. he called it 
Manhattanhenge, which in 2013 became an official English word. 
Gradually since then more and more people on their own watch the 
sunset. Today three or so myriads pour into the streets during each 
evening, They clog the streets, obstruct traffic, cause crowding. We 
saw a rare event from 2014 when the nearly full Moon rising in east 
while the Sun was setting in Manhattanhenge. This was a soft 
selenehelion, a hard one being an eclipsed Moon at sunset/sunrise. We 
saw on in 2018 at sunrise.    We cautioned against reckless watching. 
The Sun can be brilliant enough to distract attention from surrounds, 
and there is always the danger of getting bumped or worse by cars. 
Takeaways were the charts of sunset point during the year, historical 
maps of new York, Manhattanhenge plotted by astrology software, 
diagrams of selenehelion. 



Sky News

    SpaceX on May 24 (UTC date) orbited first batch of Starlink 
satellite grid. It's a brigade of 60 sats, joined over next couple 
years by some, uh, 11,000[!] more around Earth for multiple functions. 
In sky they look like a 'train' chugging thru the stars. Reports as at 
late May rank them as 4-6 magn with occasional passes of 2-3 magn.
