General News 
 ----------
    I clarified the meaning of the notations in the 'index of events' 
section. Please recall that NYC Events ended the 'XXX' notation a 
couple years ago. I also renamed the 'ongoing conditions and 
situations' section to 'ongoing and continuing events'. 
    NYSkies freshened its web homepage to remove aged material and 
clean some text. It notes that PazMiniBits and SpaceWalk are suspended 
with their last issues left in place as examples. 
    May 2017 is the ABSOLUTE AND UTTER LAST CHANCE to enjoy the 
Ringling Brothers, Barnum and Bailey Circus!  And that chance is in 
NYSkies land!! The last of the greatest show on Earth plays in Nassau 
Coliseum on May 12-21. Some dates/hours may already be sold out.  
    Gullivaer's Gate is a new long-term, maybe permanent ,exhibition 
in the Theater District of Manhattan. It opened in mid April for 
preview at reduced ticket price, then goes full show on May 9. GG 
displays in exquisitely detailed miniature models many iconic 
buildings and places thruout the world, with a special area for New 
York City. See under 'ongoing and continuing events'. 
    Governors Island opens in 2017 on May 1, a month earlier than 
previously. Ferries run every day from Manhattan, on weekends from 
Brooklyn. 
    World Science Festival runs 31 May-4 June in 2017. It stages a 
formal opening on the 30th with a black-tie theater/dinner/dance for 
Festival supporters . Please lay out your plans carefully because 
events may run concurrently or with too short time between them. See 
under May 31. 
    NYSkies at World Science Festival this year has a new function! In 
the stead of fielding an exhibit at the washington Square science 
street fair on June 4th, we provide technical and reference services 
at the starviewing in Brooklyn Bridge Park on June 3rd. Particulars 
under discussion with the Festival. 
     Astro Soc of New haven no longer uses Bethany Observatory, Yale 
University. Club does public starviewing at parks and beaches near New 
Haven, detailed in its web. 
    I moved Institute for Advanced Study to 'S/O' in case it opens a 
new season of seminars or similar meetings in the fall. It apparently 
had none in the 2016-2017 school year. 
    Institute for Study of Ancient World has a few remaining cultural 
talks in May, as noted in the 'index'.  Mistaken advice earlier had 
ISAW finishing its lecture series in April. 

City News 
 -------
       Several NYSkiers sat a short-notice lecture about Iohannes 
Kepler on 30 march 2017. It was at Bard Graduate Center, UWS MH with 
some 20 scholars attending. The presentation discussed Kepler's work 
in the 1590s, prior to his planetary motion laws. Kepler was already a 
COpernicus advocate and tried to show that the planet orbits fit into 
a set of nested polyhedra. Besides making drawings of the polyhedra, 
he built modles and mechanisms with them. 
    Penn Station was hit by rolling delays and service cuts, affecting 
all rail traffic thru it. On April 4, 2017, an Amtrak train derailed 
in the yard west of the depot, usually a minor incident. The train 
happened to rip out equipment tied to 8 tracks in Penn Station, 
slashing capacity for Amtrak, LIRR, and NJ Transit. While repairs are 
underway, expect service changes, delays, suspensions. 
    NYSkies Astronomy Seminar on 7 April 2017 examined the astronomy 
features of astrology software. By the 1990s astrology programs were 
using the same ephemeris algorithms as for astronomy, both producing 
the same planet and lunar data.  Astrology concentrates almost 
exclusively on the zodiac, represented in the classical 'wheel' chart, 
horoscope' as a circle graduated in signs/degree scale. Planets are 
marked by their symbols. The horizontal divide thru the center of this 
zodiac is the observer's horizon. The half above the horizon is the 
observer's sky, that below is hidden. At a lance we see which planets 
are up or not and the angular displacement among them. Some programs 
have a central angle dial to read out the elongation between any 
points in the zodiac, a feature crucial for astrologers but missing 
for astronomers. The inclination of the ecliptic is shown by the 
location of 'medium coeli', the crossing of ecliptic with local 
meridian. it is generally not centered at the top of the wheel but is 
shifted left or right. A left shift means the ecliptic runs in the sky 
more southeast to northwest; contrary for a right shift. The Moon has 
usually two additional markers: the apogee of her orbit and the 
ascending node. Both clue the astronomer to the Moon's latitude from 
the ecliptic and speed and angular size in the sky. When a new or full 
Moon is close to the ascending node, or opposite at the unmarked 
descending node, an eclipse is possible. Some program display info 
about immediately upcoming eclipses. Some programs mark the place of 
the previous and next full/new Moon, to judge the dates of dark Moon 
during observing hours. Astrologers monitor not only the instance of 
conjunction, or other alignment, but also the speed it develops and 
dissolves. Each planet in astrology, considering it as a bug on a flat 
sky, has a aura or 'orb' around it. When the orbs of two planets first 
touch the conjunction begins, when in the sky the planets are treated 
as somehow associated. Equality of longitude is the 'realization', the 
only event usually noted by astronomers. When the orbs break away the 
event is over, the planets no longer look associated./  Some programs 
generate charts for the event with the one planet 'attacking' the 
other, then 'retreating'.Astrologers note the start and end of 
retrograde, but astronomy software commonly don't show which state a 
planet is in. The wheel chart flags retrograde planets with a 'r' next 
to its symbol. A powerful astrology tool, not found in astronomy 
software, is a query for an arbitrary event. By keying in, thru a 
database-query code, a desired configuration of planets, the astrology 
program hunts up and tabulate instances of the configuration. 
Astronomy program do this for only a certain canned set of alignment, 
almost all with the Sun. Takeaways were several wheel charts labeled 
for different astronomy features, comparison of wheel to regular 
skymap, examples of event query, speed-position chart of planets. 
    The NYSkies astrosocial on 2017 March 31 was rained out. I was the 
only NYSkier for our delegation. An irritating steady rain held others 
away. In total there were only 6 visitors, three being students of 
ISAW. The tour explored several of the exhibit's sundials and 
calendars to illustrate cosmic view of the Greek and Roman world. 
    Ifeomia White-Thorpe, Morris Hills HS,Rockaway NJ, on April 5, 
2017, won the last of all eight acceptances for Ivy League colleges! 
She received several earlier in March-April but the final one, for 
Harvard, won her the clean sweep. The schools are Brown, Dartmouth, 
Columbia, Cornell, Harvard, Princeton, U of Pennsylvania, and Yale.  
    The new network of city-operated ferries starts on May 1 with the 
Rockaway route. It runs from Bh 108 St and Jamaica Bay,stopping at 
Brooklyn Army Terminal and Pier11-Wall St. Service has all-new 
catamaran boats with food service and WiFi. Fare is $2.75 with ferry's 
own tickets, not MetroCard. Transfers are allowed to other ferry 
routes but not to the City transit system. Four more routes start up 
in summer-fall 2017. 
        On 31 March 2017 ~19:50 EDST a manhole exploded in broadway at 
12th St, Manh. Caused by festering underground fire, the blast 
shattered windows along adjacent streets, including Strand books on 
the corner. Several streets were closed for repairs and Broadway 
subway line was closed for several hours. 
    On 13 April 2017 ~06:45 EDST  a downtown M101 bus burst into fire! 
The driver hobbled it to Lexington Av & 45 St,  where he discarded the 
riders. The fire consumed the motor bay and took firefighters about an 
hour to put out. Bus will be salvaged for spare parts else where in 
the vehicle. 
    Besides train problems at Penn Station, a stampede of some 10,000 
riders erupted on 2017 April 144 ~18:30  EDST. An Amtrak police downed 
a unruly man in the waiting room with a stun-gun. The gun-like device 
and its zap-crackle sound were taken as gunshots by rush hour crowds. 
Mobs in fleeing the depot caused at least 16 injuries from falls and 
bangs. On street, shouts of gun fire filtered into Macy's store, 
forcing a brief lockdown. Stampede was subdued by several police 
forces. 
    NYS MTA in early April 2017 began investigating Daniel Brucker, 
about possible privately-run tours of Grand Central Terminal. Brucker 
is Director of Tours, taking groups along GCT-approved tours thru the 
depot's public and off-limits areas. Some NYSkiers took one of his 
walks, like on March 25 with a subway fan club. He is suspected of 
doing tours on his off-days without GCT knowledge, with stops at 
certain off-limits areas. Brocker is suspended during the 
investigation. 
    NYSkies Astronomy Seminar on April 21, 2017, discussed lunar 
observing. We treated the motion and position of the Moon in the sky 
several sessions ago and now looked at the lunar topography. It really 
requires at least a good binocular to appreciate the surface details 
of the Moon, there being few positively discernible by bare eye. We 
noted the sense of directions, according as we treat the Moon as a 
flat disc on the celestial sphere or a separate world.  Before the 
space projects, we only used the flat disc directions, the side of the 
Moon facing west in the sky is the western limb; east, eastern limb. 
Older lunar litterature adhaered to this convention. As a globe in 
space, when we starting sending spaceprobes to the Moon, the side on 
the east in the sky is the western limb; west, eastern. In the 1970-
1990 period lunar authors employed the one or the other, commonly with 
no notice of which. An other quirk was that traditionally astronomers 
placed south at top of photos and diagrams, matching the classical 
inversion of images in simple refractors. When the Moon is regarded as 
a globe, north is at top. Current lunar references have a north-up 
placement. in spite of the direction shift, older lunar material is 
still valuable for observing from Earth with small telescopes. Because 
the Moon has no air, there is no aerial perspective or soft shadows, 
or diffused sunlight. The scene is gross light and shade, making it 
hard to correlate a map with the scope view. The scene changes during 
the lunar day from sunrise, thru midday, to sunset. We suggested a 
exercise of photographing a landscape repeatedly during a sunny day, 
sunrise to sunset, like from a high floor window. The features look 
radicly different under the changing Sun angle. The line of 
sunrise/sunset is the terminator. For evening viewing the sunrise 
terminator is on the disc; morning, sunset. Some lunar observing 
programs have a database of mapping  from an orbiting probe like 
kaguya, Clemetine, LRO. The program renders the data into 
photorealistic displays, with appropriate shading and shadows. This 
is, a recent innovation of software authors,.  The web has many 
atlases and maps of the Moon, some digitized from former print 
editions. The plates are downloadable graphics which can be printed or 
examined on screen. We saw the effect of libration to nudge craters 
and maria to and from the lunar limb. The value of libration, in 
latitude and longitude, is the lat-lon on the Moon's selenographic 
scale that is centered on the disc. Or it's the lat-lon where Earth is 
in the zenith of the lunar sky. A good lunar software incorporates 
libration in the display for a given date and hour. Even a small scope 
may amplify the Moon's light to annoy or dazzle the eye. For casual 
viewing, the scope can be fitted with a subdiameter aperture made of 
cardboard. Or, to keep the telescope's full resolution, place a small 
ND1 photographic filter in the eyepiece tube.  We chatted up the 
origin of the Moon and wondered why it took so long to realizw that 
the massive bombardment on the Moon must also fall on Earth. on Earth 
weather, tectonics, earthquakes, glaciers, human land modifying, 
vegetation, more erase or hide the craters. Takeaways were map-photo 
comparisons, views of Copernicus crater at various points in the lunar 
day, set of evening Moon phases with and without feature labels, 
cartographic lunar atlas, examples of libration. 
    NYSkies starred at both NEAF and Earth Day in April 2017. Our 
table was handled a continual flow of visitors. For some reason this 
year thee was a higher interest in New York astronomy then normal, 
with banter and chat about the astronomy in the  City and other towns. 
I presented my talk about Manhattanhenge at NEAF on April 9th, 
igniting additional inquiries about new York astronomy. Since many 
visitors are convenient to the City, we may see them at our Seminars. 

 Sky News 
 ------
    April 2017 was a lousy stargazing month, with most nights clouded 
over. many were also rainy. The adverse sky killed off the omega 
Centauri challenge and GLOBE at Night. I heard of wide-spread 
cancellations of regional starviewings due to recurring clouds 
   The final round of GLOBE at Night for NYSkies, 2017 Apr 18-27, was 
almost a total cloud-out. On the two evenings of clearish sky, on the 
18th and 23rd, twilight dulled Orion to only 1st or 2nd magnitude 
transparency. GaN dates  avoid evening Moon, which were in mid-late 
April, when Orion was edging into twilight. 
    Observers are watching Jupiter, well up in southeast at nightfall 
in April 2017. Some were surprised that the moons weren't lined up 
neatly across Jupiter. Jupiter's moon plane this year is titled a from 
edge-in, causing the moons to pass on the north or south side of the 
Jovian disc. 
    Midnight observers are starting to inspect Saturn in Ophiuchus-
Sagittarius. He'll be in southeast at nightfall in mid May. 
    Occultations of Hyades and Aldebaran continue thru spring and 
summer 2017, now in the predawn sky. Astronomers are already psyching 
up for the Porrima occultation in July! We  then see TWO occultations 
at once. 
    The omega Centauri challenge in April 2017 was killed by cloud and 
haze. No night was clear enough for a good chance to see this cluster.  
2017 is the first year we extended the program into April. Until now 
it was only in May. The challenge continues into May but twilight may 
then interfere. See under May 1. 
    The spring season for seeing the Milky Way from within the City 
opens on May 1st. Hopefully weather will improve to let the brighter 
patches of the summer Milky Way be seen in predawn hours. See under 
May 1. Season runs thru June 30.
