NYC EVENTS FOR APRIL 2017 
 -----------------------
 John Pazmino      -
 NYSkies Astronomy Inc  
 @nyskies.org  
 www.nyskies.org 

    The following astronomy activities in the commuting ring enclosing 
New York City are operated by various organizations. A few cultural  
items of special importance to City astronomers are also included.  
    Altho NYC Events confirms the listed items, they are subject to 
change by their sponsors. Check with their contacts. Let the sponsor  
know that you learned of its event thru NYC Events.  
    Frequently asked questions and explanation of NYC Events is at 
'www.nyskies.org/nyc-faq.htm'.  
    You may ask for previous NYC Events thru 'nyskies@nyskies.org' 
because only the current issue is in the website. It is replaced by  
next month's issue.  
    For events which missed NYC Events, check the NYSkies Yahoogroup 
forum. Join NYSkies by visiting 'www.nyskies.org/yahoo.htm' and 
picking either the email or website option.  
    All hours are Eastern Daylight Savings Time (UT - 4h). 

General notes 
 -----------                           / 
    'whole City' means the event has no specific or dedicated place. 
It may be enjoyed from the whole NYSkies territory or at a number of 
individual places. Celestial events are typicly 'whole City' events.  
    'all day' means the event is continuous or repeating during the 
open hours of the host facility. Facilities may have limited hours per 
day or days per week. Check with the event contacts.  
    'adv regn reqd',for 'advance registration required/requested' 
means that the event requires or requests signing up before the event. 
You must have your ticket in hand at the gate. There could be a 
deadline some days before the event, after which no more signups are 
accepted. Check with the event contact for specifics. 
    Prices cited are the 'rack rate'. You could qualify for discounts 
 As may be offered by the sponsor. Besides the base price there may be 
noptional extra fees to consider. 

Earth Day and NEAF 
 ----------------
    Recall that in 2016 NYSkies missed both NEAF and Earth Day. I was 
in rehab from my car accident for these events. 
    We're back in working order for 2017 and will have booths for the 
two shows. You and astronomy fiends can stop by, chat up about the 
stars, and, yes, take in the other attractions. 
    NEAF is Sat-Sun 8-9 April in Suffern at Rockland Commty Coll.    
It's am easy ride by intercity and street buses from the Port of 
Authority depot. Buses to/from Suffern depart hourly; local buses, 
half-hourly. 
    Please fetch schedules from ShortLine bus company and Transport of 
Rockland NOW to plan your trip.  The Shortline timetable has several 
panels, one for Suffern runs. It looks like all buses end their run in 
Suffern. STAY AWAKE! Some buses continue beyond to West Point and Bear 
Mountain, as shown in other panels. Sleeping past Suffern can cause no 
end of distress. 
    Note that NEAF closes at 5PM each day. This allows plenty of time 
to be back to the City in daylight. 
    Earth Day is  April 18, a Tuesday. Usually the festival is on a 
weekend, which in some years conflicted with NEAF. We are in Union 
Square, northwest corner, where Broadway takes a jog around the park. 
The booths are in tents in case of rain or extreme sun. 
    The green, gray ,yellow lines stop under the park with exits in 
the midst of the booths. Other lines offer transfer to these three or 
stop a couple blocks away from the park.

skyscraper, Big Bend'. It's two towers ~100m apart rising to ~550m 
height. They are joined together across the top by a semicircular 
section whose crest is at 600m elevation. No location presented but 
pictures seem to place it on Central Pk S, 6-7 Avs. The intent is to 
count floors continuously along the inverted U-shaped structure, up on 
one leg, thru the arch, down the other, for total length of some 
1,300m. No one yet bought the plans to build it. 
    Target store on 2017 March 19 unveiled new manhattan outlet at112 
W 34 St, across from Macy's store. It concentrates on groceries and 
clothing as the flagship unit in the chain. It has modest floorage, 
only one acre, about the same as other Manhattan units in TriBrCa and 
Harlem. Open is set for October 2017. 
    On 19 March 2017 NYS MTA adjusted transit fares and bridge/tunnel 
tolls. While fare increases aren't pleasant, this round is 
surprisingly mild. The base, 'token', cash fare stays at $2.75, $36.50 
for express bus fare. 7 and 30 day MetroCards are  only a couple 
dollars more. Most increase comes from reduction in stored-dollar 
bonus from previous 11% to current 5%.  See under April 1. 
    NYSkies Astronomy Seminar on 2017 March 3 explored Jupiter, now in 
our night sky. We traced his movement thru the zodiac, seeing how his 
apparitions slide about one month later each year. In April he is in 
his retrograde loop, heading toward Opposition on April 8. In the sky 
Jupiter wanders between Spica and Porrima in Virgo. Thru even a small 
scope the four large moons of Jupiter are visible. Because their 
orbits are almost edge-on to our sight, the moons oscillate east-west 
across or behind the planet's globe. We know them now by name but 
until the 1960s we merely called them by roman umber, I-IV. Galileo 
first showed the moons but Marius saw them in few months earlier, with 
no publication, and ave them the present names. The sudden shift from 
number to name was compelled by the space program when it was far more 
credible to send probes to Eruropa than to moon II. The moons can be 
eclipsed by Jupiter's shadow, hidden by the globe, crossing over the 
disc, and the moon's own shadow can transit over the disc. Small 
scopes often lose the very moon in Jupiter's disc but can easily 
follow the shadow it throws onto it.We followed the history of 
navigating by Jupiter's moons, which never worked well with the shops 
and instruments of the 1600s and 1700s. The various events were 
calculated for a home longitude and the timings on the ship compared 
with them. The time difference is the longitude of the ship from the 
home port. We were awed at how huge the Jupiter satellite system is. 
In any ordinary scope we see only the four giant moons, the Galileo 
moons. Jupiter has 70ish moons, hardly clearing out its vicinity, all 
being far too faint for small scopes. These orbit out several millions 
of kilometers from Jupiter to fill an area several degrees diameter in 
the sky. We examined this scene with Jupiter near Hyades & Pleiades 
 and all of his moons turned on. Medium scopes revelal the belts of 
cloud on Jupiter, torn into latitudinal bands by his rapid rotation. 
Jupiter's day is about 10 hours, with gradient from equator to pole. 
To schematicly describe the orientation of Jupiter we have FOUR speeds 
of rotation. System I covers the equatorial zone of Jupiter. II is for 
the rest of the planet. III is the rotation of a radio-emitting 
hotspot deep inside the planet. This spot is detected by simple home 
radio telescopes. The fourth rotation is for the Great Red Spot and is 
not a consistent rate. The GRS speeds up and slows down year by year 
and its longitude must be set from observation at the start of each 
apparition. Jupiter conjuncts frequently with Venus within a couple 
months of his superior conjunction with the Sun. These events are 
spectacular. specially when the two planets are close together. A 
couple years ago they were only 1/10 degree apart and many observers 
reported they could not resolve them by eye. Takeaways were charts of 
Jupiter's path in 2016-2018 thru Leo, Virgo, Libra; sample tables of 
moon events, one using the moon numbers, the other with 
names;simulated telescope views of the moons and disc; a February 2017 
photo of the GRS which was thin a d weak;input panel from planetarium 
where the current GRS longitude is keyed in; sky scene of Jupiter's 
entire moon system in Taurus.
        A go{ro Karma Quadcopter drone crashed thru window of 
Manhattan  apartment on 265 February 2017 ~17:45h EST. It died on 
floor a meter from woman tenant working on her computer. She was not 
injured. Incident was at the 27th floor of tower in Waterside Plaza on 
East River. NYPD and US FAA are investigating. Flying drones is banned 
thruout the City except in designated parks outside Manhattan. 
    NYC DOT on 15 February 2017 presented new ferry services for City 
with brand-new small boats under construction.  Some routes start in 
summer 2017, rest in spring/summer 2018. All routes end at Poet 11 
(Wall St) or 34 St (Kipps Bay). Many stops are at former ferry piers 
in Brooklyn and Queens. 
    News broke on 26 February 2017 about NYC mayor deBlasio's scheme 
to 'nationalize' certain coop apartment buildings for affordable 
housing. In 1980s certain buildings in City hands were sold to private 
owners under a complex set of conditions, including a provision that 
the City on its own can modify these conditions at will. deBlasio 
wants to capture 1,200 of these buildings for municipal supervision, 
screening of coop buyers, and capping sales price of units, among 
other rules. Plan would create ~30,000 units within reach of low-
income families, who then are under city jurisdiction, not the private 
owners. Liberals and leftists cheer the plan as an American 
realization of progressive methods achieved elsewhere in world.  
    MetroNorth Railroad on 25 March 2017 started search for a supposed 
master clock from former Grand Central depot. It is said to be the one 
that ceremoniously initiated time zones in the US and was apparently 
set up somewhere in the present Terminal. 
    MetroNorth Railroad on 2017 march 25 assures that the historic 
arrival model and blackboard in the Biltmore Room will be safe-keeped. 
The hall will be reconfigured for adits to new LIRR decks now under 
construction. MetroNorth doesn't yet know how to remount the board and 
model else where in the Terminal. 
    NYSkies Astronomy Seminar on 17 March 2017 discussed globular 
clusters, specially in the spring sky. We learned how globular 
clusters are sprinkled all over the sky, being a cloud surrounding the 
Milky Way galaxy, and also in a bunch in the galactic center. We 
examined the current theory that globular clusters may be the remains 
of small galaxies that got too close to the Milky Way. Only their 
dense cores survive as a spherical ball of stars. Eventually these may 
settle into the galactic core and be digested into the overall Milky 
Way population.We learned how globular clusters were at first classed 
as nebulae because early telescopes were too small to reveal the 
component stars. Herschel first resolved these nebulae into star and 
realized they must all be spheres, globes, made of stars, whence his 
name 'globular clusters'. Spring has many globular clusters, some seen 
in binoculars and others needing a large scope. One special cluster is 
omega Centauri. Altho it is one of the brightest clusters, 3rd 
magnitude, its far south declination keeps it no more than two degrees 
over the southern horizon at culmination. it is then dimmed by thick 
air. We discussed the prospects of seeing omega from the City. It is a 
challenge, calling for excellent telescope skill and clean dark 
horizon. This year we start he omega challenge in April to give more 
chances to see the cluster. The season continues into May, when near 
the end of the month evening twilight gets too bright. We saw how 
modern instruments capture details not previously discernible in 
globular clusters. The typical photo has a thoroly whitened out center 
where the star images overlap and fill in on the film. Today's digital 
imaging captures the individual stars in the close clusters and 
collect information about each. We studied an HR diagram of omega 
suggesting that there are two generations of star in the cluster. The 
diagram has two Main Sequences, offset due to different metal content 
in the stars. Maybe the cluster is really a victim galaxy with its own 
history of star birth and evolution? We reminded that the best season 
for globular clusters is summer, when the galactic center is in view. 
Messier found almost all of the brighter specimina in Scorpius, 
Sagittarius, Ophiuchus. Some two dozen are within reach of small 
scopes from the City under clear sky. We learned that globular 
clusters are targets of practice for observing newly found comets. The 
clusters resemble the nuclei of comets when still on their way toward 
the Sun before the coma and tail develop.By successfully finding and 
examining globular clusters we get confidence when hunting for the 
comet. Takeaways were finder charts for three spring clusters, 
articles and maps for the omega challenge, articles about omega 
Centauri, charts of globular clusters in seasonal sky.
    The final shows of Ringling Brothers circus may by now be fully 
booked. Some readers tried to get tickets  and were turned away. 
Circus reported in late February 2017 that this final season scored 
the largest attendance in its history, even tho the show is watered 
down without the elephants.

    March 2017 was a lousy month for observing, except for an 
occasional clear night. Most nights were cloudy, some with rain or 
snow  Observation of the Venus inferior conjunction and GLOBE at night 
were severely interfered by clouds. 
    The blizzard of 2017 March 14 dropped 18cm of snow in Central 
park, far less than the predicted 50cm. It did yield sleet/slush and 
freezing temperatures. Rest of NYSkies land got 30-60cm snow, white-
out, coastal floods Rails and roads were disrupted during the day with 
recovery in late afternoon thru night. 
    Many readers got their first good sight of Jupiter on 2017 Mar 14. 
Clouds from the snow of the 14th slided away from the City, like a 
roll-off roof, in early night. It opened up a clear sky with the  
almost full Moon in east-southeast. Jupiter, a couple degrees upper-
right of the Moon, thrilled observers, giving a welcome relief from 
the all-day clouds, rain, sleet, snow. 
    The shift to daylight time on 2017 March 12 passed thru with 
almost no ill effect So many clocks today  are tied to a network or 
other global time service. They indexed to EDST without manual 
handling. Only the remaining older clocks not connected to networks 
required twiddling their dials by hand. 
    Pi Day on 14 March 2017 was snowed out. A;THO the fall was less 
than forecast, many schools and offices were closed for the day, 
cancelling planned Pi Day celebrations. The second Pi Day of the year 
is 22 July, when there probably will be no snow. 
    My own results from trying to observe Venus in both morning and 
evening during her March 2017 inferior conjunction. I used binoculars 
for all attempts. I did not observe for morning of the 23rd and was 
away from the sky for morning of the 25th.  I achieved only one 
positive sighting of Venus, the evening of the 23rd. All other times I
tried the weather was adverse against making an observation.
    -----------------------------------------

    Earth Hour was 2017 March 25 20:30-21:30 EDST for NYSkies. The sky 
was thoroly overcast for most of the region. According as the normal 
level of luminous graffiti for each observer, hotspots reflected from 
clouds. In my case there were no significant hotspots and no 
alteration of them during Earth Hour. March 25 was also a GLOBE at 
Night date. I let my  21:00 observation during EH count for GaN.
