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. 

Solar eclipse on 21 August 2017 
    The total solar eclipse that sweeps across the United States on 
Monday 21 August 2017 is a large deep partial eclipse in NYSkies. The 
Moon at mid eclipse covers the south, lower, 71% of the solar disc. 
See under August 21 for timetable for the eclipse for Manhattan. 
    This eclipse requires at all times solar protection because the 
Sun's face is always exposed. At read time it may be tough to obtain 
new filters due to the massive demand for them, nut push hard at 
vendors and large photography stores. Or observe by projection 
    Mind well the summer weather. You may be assaulted by haze, hear, 
moisture, rain, insects. Wear a hat and loose airy clothes, bring 
water or juice. You may duck into shelter for cooling off or rest 
because there is no special instant to worry about for this eclipse. 
    As at issue time there are few public eclipse watches announced. 
Possible reasons are the mass migration of astronomers into the 
totality path, leaving too small crew to carry out a public event. An 
other is that there is likely a public viewing for the Perseid meteors 
about 10 days earlier that could weaken chances to mount a second 
major event for the eclipse. 
    Please circulate among astronomy centers, using the contacts in 
this NYC Events, for late-breaking news of public eclipse watches. 

Perseid meteor shower
    On 12 August 2017 ,owl thru predawn hours in NYSkies, is the 
annual Perseid meteor shower. With so many astronomers leaving the 
NYSkies turf to view the eclipse, thee could be a shortage of crew for 
a public Perseid watch. The shower is also impeded by a 
 waning gibbous Moon. Check with astronomy centers, via the contacts 
in their entries hee, for news about public viewing of the shower..

General News
    NYSkies Astronomy inc renewed its domain and web hosting thru year 
2026. We got a healthy discount from the year-by-year rate and 
simplifies our record-keeping. 
    Please verify events falling a week either side of August 21st! 
With so many astronomers in NYSkies land migrating to the total 
eclipse on that day, there could be a shortage of staff to run full-
featured events. Most eclipse travel spans  five or so days on each 
side of the august 21. Most listed events were set up months ago, 
before the full attraction of this eclipse was recognized. 
    NcCarthy Obsy meets on August 11, a Friday, not the normal 
Saturday. Inquire at McCarthy to verify this date. It could be a typo.

    On 4 July 2017 Joey Chestnut consumed 72 hotdogs in 10 minutes  at 
the Nathan's hot/dog eating contest. That's 8.33 second/hotdog!  The 
feat was both a new world record and Chestnut's 10th victory. He won 
every contest since 2007, losing only once in 2015. 
    The Penn Station 'Summer of hell' started on July 10. LIRR and NJT 
skipped trains, rerouted others, set up ferries and buses. LIRR and 
NYC Transit cross-honored fares. NJT and PATH also did. There were a 
couple derailents, signal glitches,  power cuts near Penn Station, 
adding to travellers's troubles. Hopefully the rebuild work will 
complete by end August. 
    Amat Obsrs Soc held its repeat 'City of stars' tour on 2017 July 
1, The day was hot and muggy, exhausting the group after its last stop 
at peace Park, after when every one called it a day. A rain missed 
soaking three group because it fell entirely during the bus ride from 
Columbus Cr to upper Manhattan. A couple NYSkiers took the walk, 
covering about 13km . 
    My article about a United Nations conference on protecting 
cultural structures attracted a lot of comment. The most common one 
asked why I didn't mention the role of UNESCO. It has several offices 
working for documenting historical places. The short answer is that 
UNESCO was not cited in the written or verbal material of this 
meeting. When composing my article, I learned of a far deeper reason 
UNESCO was absent from the meeting. I'm assembling a new section for 
the piece. Hen completed and melded into the article, I'll let you 
know. The current piece is at 


    NYSkies Astronomy Seminar on 2017 July 7 discussed Manhattanhenge. 
It would start on July 9 but we planned to watch a preview outside our 
room in 14th St. We were rained out.  We watched a slideshow detailing 
the mechanics and hazards of Manhattanhenge. it is usually possible 
for any town to find a sunset, or sunrise, alignment with some long 
sightline and assimilate it into a town's civic or cultural life. In 
New York the alignment is with the cross streets on Manhattan, aiming 
into azimuth 299 degrees. This happens on May 29-31 and July 9-11 each 
year. The range of dates allows for the solar diameter and width of 
the street. We saw how from the layout of the streets in 1811 thru 
about 1880 there probably was nothing special about the lined up 
sunset. The skyline was low, five or six floors, to allow a view of 
sunset when away from a street lineup. We saw a scene of the City from 
te 1850s showing the low profile of the buildings. In the 1870s-1880s 
several developments changed the cityscape. Some were pumping to raise 
water supply to floors above 5 or 6, acceptance and confidence with 
elevators,use of steel framework construction, building of rapid 
transit. All made it feasible to build the skyscrapers  that hem in 
the streets. Only a thin sliver of sky is visible along them. The 
sunset is not seen unless it fa;;s within the sliver, a sight that 
reminds of the alignment at Stonehenge. The Stonehenge effect was an 
in-house feature for astronomers but the public took little notice. 
When in 2002 Neil Tyson, Hayden Planetarium, highlighted the effect, 
the general public started to look for it. Attention gradually grew 
until 2010. By then digital imaging was well diffused in society to 
let any one, not just photographers, capture pictures of the sunset. 
Then after the twice-yearly event attracts myriads of viewers, many 
coming from off-island specially for the show. Tyson coined the term 
'Manhattanhenge', that in 2013 was inducted into the language by the 
Oxford English Dictionary. Being that Manhattanhenge is viewed by 
standing in the middle of a cross street, with a clear sightline to 
the Hudson River. This puts the viewer in the path of road traffic, 
which is not restrained by Manhattanhenge.  There can be accidents 
between cars and people, some fatal. Because Manhattanhenge lasts only 
three days each time and for only a half-hour on each day, there is no 
significant increase of traffic deaths/injuries in May and July. An 
other hazard is the dazzling Sun on clear days. it is dangerous to 
stare at the Sun normally, and more so when something interesting is 
happening with it. You are distracted from street activity to become a 
traffic hazard. We wanted to preview Manhattanhenge outside in 14th 
Street, like we did in the June 2nd meeting. It was raining. The 
second topic of this Seminar was eclipse viewing methods. We examined 
front-end filters for telescopes, densely-developed B&W film, eclipse-
rated cardboard eyeglasses, and mirror projection. We all knew that 
NOW [July 7] was the time to start getting the filters for scopes and 
cameras. Supply could run out from the immense public interest in this 
coming August eclipse. We knew that NOW is the time to start 
exercising with eclipse devices under ALL days with some sunlight. You 
must learn thoroly how to operate your device under all sky conditions 
possible in a summer day. We knew well not to try a homemade filter, 
like an unfolded shiny snack bag or dark-colored plastic. Takeaway was 
examples of sunset alignments, low-profile scenes, sunset azimuth for 
cardinal dates and Manhattanhenge, development of New York skyline, 
scenes of previous Manhattanhenge shows, sun shining thru Stonehenge 
pillars, street hazards for viewing Manhattanhenge. 
    Thank you, Carrie Ho and Jim Henderson for the pizza, soda, water, 
and candies at the July 7, 2017, Seminar. The refreshment made for a 
lively cross-talk and banter among us astronomers. 
    A travelling exhibit of Sistine Chapel reporductions sat in the 
Oculus on 2017 June 23-July 23.  A dozen free-standing panels carried 
detailed photos of Michelangelo's paintings from te Chapel in a roped-
off area on Oculus main deck. All can be seen well from outside the 
rope but a $20 admission let viewers inside for closer look  with an a 
recorded narration. 
    Sotheby's auction house on July 20, 2017, out on the block space 
artifacts, mostly from US and USSR human flights. Thee were also 
historical photographs of the Moon from the 19th century and several 
models of spacecraft. As at issue time I heard nothing from any 
NYSkiers winning any bids. 
    NYSkies Astronomy Seminar on 2017 July 21 prepared us for the 
August 21 solar eclipse. We took in a slideshow of solar eclipses, 
then explored the August eclipse with takeaways. The show demonstrated 
how solar eclipses occur, their frequency, relation to lunar orbit. It 
then showed the avarious kinds of eclipse, like the partial one for 
August in New York. It then illustrated features of a total eclipse 
for those of us heading to the totality zone. The slideshow was 
delayed from a computer malfunction, which Greg Homatas fixed. We 
discussed last minute preparations for equipment and travel.  We hoped 
there will be large sunspots, like the ones during the days before the 
meeting, to add interest to photographs. Most of us were practicing 
with their devices to be confident and proficient during the eclipse. 
Some asked about staging an eclipse party at home. The idea is a good 
one but requires thoro smarts about the neighbors, housing, viewing 
space. Any party should be low-key with a few snacks and soft drinks. 
We studied the takeaway, some duplicates of the slideshow frames, It 
was much easier to inspect the diagrams and charts on paper than to 
remember them on screen. SOme of us fumbled the UT-EDST  conversion. 
Most eclipse tables and diagrams are in UT, or GMT, which must be 
shifted to the timezone of the observing site.  One takeaway  map 
intrigued many. It was the totality path in South Carolina with 
duration contours. On the centerline the duration was longest, two and 
something minutes. Toward the edge it shrinks to mere seconds. Most 
eclipse chaser strive to stand on the centerline for the maximum 
duration, but roads and topography may prevent that. 
    Public notice of the 2017 august 21 solar eclipse suddenly erupted 
in late July 2017. Several newspapers had stories about it, some with 
viewing cautions and advice. Most warned that with the huge population 
living within a day's drive or ride from totality, this eclipse could 
be  observed by far and away the most people in history. Some warned 
about potential traffic clogs on roads.  
    After the 21 July 2017meeting sharp-minded NYSkiers asked if there 
was something wrong with the zodiac chart of this eclipse in the 
takeaway. It was drawn for 18h45m EDST, not UT. I entered UT  into the 
software to produce the chart, thinking it would slide it into EDST. 
It took the input hour as EDST and cut the chart,. It is four hours 
later than I wanted. A corrected  replacement chart wa sent to the 
NYSkies maillist. Astronomers only reading NYSkies thru the 
Yahoogroup, where file attachments are stripped, may get one from me 
by direct email. 
    Space & Science Fest at intrepid Museum on 2017 Aug 3-6 features a 
new circulating exhibit from NASA. It's 'Summer of mars experience' 
with a concept model for a future robotic Mars rover. The exhibit 
tours Jersey City NJ, Washington DC an Atlanta GA, before setting up 
permanently at Kennedy Space Center. 

Sky News
    July was one of the worse months for observing. The sky was almost 
never really clear, the best being a smooth haze. Observers did get 
stable images of Jupiter and Saturn and srudied double stars. Most 
deepsky targets were severely dulled. Many days scored temps of 32C 
and higher, that with high humidity made life awfully miserable. 
    Manhattanhenge in July 2017 was observed with mixed luck. Some 
watched it thru clear hazy sky; others, broken clouds. On Friday 7 July 
2017 observers were rained out at the NYSkies Astronomy Seminar.  We 
made do with a slideshow about Manhattanhenge and a walk-thru of 
Manhattanhenge takeaways.
    Steve Lieber, NYSkies,  alerts that some eclipse-viewing glasses 
at sale are not safety-rated. They look dark enough but may pass thru 
infrared wavelengths harmful to vision. he offers one web for details, 
of many such webs about hazardous glasses. All hyphens are part of the 


Eclipse viewing devices should be obtained only from reputable 
astronomy sources.
    The rainbow splashes under Second Avenue awed everyone who saw 
them! So far they are still vivid and brilliant, but I expect that 
accumulated dirt with smother them. When I first noticed them in 
April, while riding into 2nd Av to catch an empty downtown train for a 
seat, I was puzzled why no one else was admiring them. To and most 
other NYSkiers the splashes are so dazzling. At the July 7 and 21 
Seminar I brang photos of the splashes as pass-arounds. Some of us saw 
them immediately with no trouble. Some others insisted there was 
nothing at all in the pictures. They saw just the plain wall. This is, 
erm, bizarre. I can allow that in real life the splashes affect eyes 
differently, but not those in a static picture. Maybe, just maybe, the 
cause of so little general public attention is the on the whole no one 
sees the splashes. Only certain people do?
    Some readers asked if any planets will be visible during August's 
partial eclipse. They knew that Jupiter and Venus will be up. Alas,no. 
the sky will always be in full daylight, even at mid eclipse. Perhaps 
you may fine both planets with binoculars. Under totality, do pull 
away from the eyepiece and look around the sky. At least these two 
planets should be visible, maybe some brighter stars. If so, let's 
hear about your sighting at the September 1st Seminar. 
    As the days roll by, more and more astronomers in the NYSkies 
region are travelling to the August eclipse. The totality path is 
SOOoo close to the City that it's cruel not to try for it. Some are 
doing the in-&-out trick. They are riding by bus or train to totality, 
watch the eclipse from the depot, and ride the next train or bus back 
home. According as schedules permit, there could be an overnight stay 
at the totality town.n  
    After this coming eclipse the next one for NYSkies is on 10 June 
2021 . The Sun rises almost exactly at mid eclipse, 05:32 EDST with 
about 73% obscuration. 
    The next lunar eclipse is on 31 January 2018 at sunrise. 1st 
contact is 06:53 EST. The Moon sets at 07:07, before totality begins. 
This event is a true selenohelion! 
    In mid June 2017 NASA tried several times to launch ion bursts 
into the upper atmosphere to possibly generate artificial aurorae. The 
rocket ascent from Wallops is base and the bursts would be seen from 
NYSkies in south and southeast. After a few scrubs in evening, NASA 
tried again on June 29th in early dawn. The shot was a success but 
few, if any, astronomers in the City saw the show
