    The following astronomy activities in the commuting ring enclosing 
New York City are operated by various organizations. A few cultural  
tems 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 hHours are Eastern Standard Time (UT - 5h). 

Betelgeuse is fading! 
 --------------------   In fall 2019 Betelgeyse began fading, more 
rapidly and deeper than normally. Assessments of the star's brightness 
should be taken on every night, even in bright Moon and impaired sky 
conditions. 
    Betelgeuse is among the brighter stars, with few other stars to 
confidently judge its magnitude. Here is a table of stars in the 
Winter Hexagon to bracket Betelgeuse for a magnitude estimate. Do this 
for different sets of star. 
   -------------------------------
   COMPARISON STARS FOR BETELGEUSE 
    ------------------------------
    star  | name        | magn 
    -----+--------------+-----
    alp Ori | Betelgeuse | var 
    ---------+-----------+--------

    bet CMa | Mirzam     | +2.0 
    kap Ori | Saiph      | +2.1 
    ---------------------------
     The report emialed to me, which may beassembled weekly, gives the 
observer's name, address, contact; observing location (town or 
district). For each magnitude assessment give the date, hour, 
timezone, assessed magnitude (to 1/10 magnitude accuracy), names of 
comparison stars sued, general sky conditions. -----------------------
    Betelgeuse is well up in east and southeast at nightfall and is in 
night sky thru April 2020. 
    Our Seminar on January 3rd brief us about Betelgeuse, with latest 
news and instructions. 

 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.  
c    '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

General News
  ----------
    The January NYC Events is the hardest one of the year to compile. 
Many events are held in facilities short-staffed or closed for yearedn 
holidays. Event sponsors may also be short-staffed. Schedules for 2020 
can't get be fixed until early January. Check with event's contact for 
updates.re more '???' entries than usual. Inquire at the e 
    NYSkies renewed its room agreement with McBurney House for 2020. 
The rent notched up a little bit, still well within our budget. The 
Seminar page in our web will be updated soonest with the new schedule. 
    Hayden Plm runs two distinct series of lecture, 'astronomy live!' 
and 'Frontiers'. I list them separately. 
    Liberty Sci Ctr, Jersey City NJ, has two different planetarium 
shows, during a day's visit. Its 'Premium' ticket admits to both, 
besides a run of the museum. The planetarium is newly built into LSC's 
former IMAX chamber.
    Astro Soc of Gtr Hartford has no starviewing at Van Vleck Obsy in 
January. The next session is February 1st. 
    1There's still time to see the Bloomingdale's Apollo window 
displays and the Franklin Instt's Moon globe. Both shows end on 
January 5th. 
    Natl Musm of Math moved its January 'Math encounters' show o Tue 
the 7th. It's normally the first Wednesday of the month, whih is New 
Year's Day. 
    Holocaust Remembrance at the United Nations is Jan 27-30. This 
year is extra important for being the 75th anniversary of Aushwitz 
liberation and the spike in assaults against Jews in the NYSkies 
region. You must sign up for each event separately, there being no 
union ticket.. Advance registration and GI photo ID  is required. The 
full schedule has the sign-up links for each event. 

 City News 
 -------
    National Grid resumed hookup for new piped gas customers on Nov 
25, after working out agreement with NYS Gov Cuomo. The utility 
serves Brooklyn, Queens, Long island.  It suspended new hookups in 
July 2019 due to concern about shortfall of supply from a delayed 
pipeline in upstate New York. 
    On Dec4 Amazon began full-scale  test f cargo bikes on Manhattan. 
In place  of trucks, small packages are delivered by electric bikes 
pulling a cargo wagon. Wagon holds ~130kg load. Bike returns to depot 
to recharge and load for next run. UPS and DHL start cargo bike tests 
in early 2020. 
    NYSkies Astronomy Seminar on December 6 was a short one to let us 
get some sleep for the Philadelphia bus trip in early morning of the 
7th. We discussed deepsky objects as targets for observing, leaving 
out for now their astrophysics. We walked thru history of DSOs, for 
short, with Ptolemaeus's catalog including  a few nebulous stars. 
There were a few new ones found since the to the 1900s by eye, such as 
Al sufi's cluster of the Coathanger. Halley collected notes of known 
nebulous stars, such as Hercules cluster and Andromeda nebula. 
laCaille in mid 1700s surveyed the whole sky, first to do so, and 
listed some 40 nebulae and clusters. He grouped them as all nebula, 
all stars, mixed stars and nebula. Messier in late 1700s found 103 
nebulae and clusters, some overlapping laCaille's. His assistant 
Mecahin found more for a total today of 110. while the Messier catalog 
does not cover all the easy objects, it has a variety of targets from 
easy to challenges for small telescopes. Observing all of Messier's 
objects prepares us to look for any other target within our scope 
range. We saw that in 17th to 19th century we thought a nebula, a 
cloudy misty patch in the sky, would resolve into stars with the next 
improvement in telescope design and technique. it seemed that way 
until we discovered that many nebulae were really dust and gas with no 
stellar composition. In the 20th century we learned that many nebulae 
were really external galaxies.we related the mix of DSOs in the sky to 
the path of the Milky Way. Open cluster and most nebulae trend along 
the Milky Way band. In summer thru spring the MW is in high sky, 
filling the sky with these targets. In spring, for NYC latitude, the 
MW is near or under the horizon , removing most open clusters from the 
sky. We found that globular clusters envelop the galaxy with a 
concentration in the galactic nucleus. In summer we see the nucleus, 
filled with globular clusters, low in south where Scorpius, Ophiuchus, 
Sagittarius meet. galaxies we saw are all over the sky, being outside 
our own galaxy, with a thinning out along the MW path. Dust in our 
galaxy blocks their view. We learned several tricks for seeing faint 
DSOs such as averted vision and gently tapping the eyepiece. many DSOs 
require skill in star-hopping from a bright jumpoff star. We cautioned 
that from graysky zones we may see the cluster embedded in a nebula 
but not the very nebula. Takeaways were historical articles about 
nebulous stars, table of laCaille objects, example pictures of open 
clusters, globular nebulae, globular nebulae, article on DSOs, table 
of sample DSOs to observe, summer and winter charts of Messier 
objects. 
    NYSkiers sat a lecture at Linda hall Liby, Kansas City MO on Dec 
12! They did so by live webcast from camera in library's lecture room. 
Talk discussed separation of astrology and astronomy in 16th-
 17th centuries. 
    NYS Gov Cuomo on Dec 13 approved new statue of Mother Cabrini for 
Battery Pk, MH. Statue is reaction to NYC Mayor deBlaasio's rejection 
of honor, after his public  survey  for new statues gave Cabrini ~60% 
of vote, more than all other candidate combined. The statue will be 
near Holocaust Museum, looking across New York harbor and Statue of 
Liberty, Installation set for 2021. 
    By mid Dec 2019 the new OMNY tap-&-go turnstiles were spreading 
rapidly thryout the subway system At the Dec 20 meeting we noted that 
our own 14th St/6th Av station now has the new turnstiles. Several of 
us examined them on the way home. Turnstiles accept current MetroCard 
and also have a sweet-spot to tap a phone, with an OMNY software 
onboard, to pay fare. . 
    Larry Elder radio show on Dec 13 posed an astronomy question in 
its 'Can you beat Kurt?' segment: 'What is the name of the final human 
visit to the Moon in 1972?' Contestant answered correctly 'Apollo 17' 
but lost the game from low total score.
    NYSkies Astronomy Seminar on 20 December 2019 overviewed the 
winter stars over the City. For the yearend holidays Myrna Coffino set 
out a plate of crunchy cookies and John Gale handed out, hold your 
hat, genuine Eisenhower dollar coins! We then studied starcharts of 
the sky, looking south and northeast. The latter showed how some spring 
stars are coming into view while some summer ones were finally leaving 
out sky. We explored the Winter Hexagon and learned the distinction 
between constellations and astreisms. A couple asked why many 
asterisms are called 'Caput'. They are in the caput, head, of the 
classical figure of the constellation. We noted that stars of a given 
season or month are those along the local meridian at nightfall. stars 
of an earlier period are in the west while those of the later period 
are in the east. We can observe the spring stars by waiting a few 
hours for them to cross over to the meridian. We examined the 
arrangement of deepsky targets in the sky by their location within the 
Milky Way galaxy. Open clusters, open nebulae, globular or planetary 
nebulae hug the Milky Way band. This runs southeast, thru overhead, to 
northwest. Globular clusters are sprinkled all over the sky, being in 
a cloud surrounding the galaxy. Galaxies are also all over the sky, 
beyond our galaxy, but there is a shortage of them along the ME band. 
Dust in our galaxy blocks view of other galaxies. We discovered that 
in winter we look toward the outer edge of the Milky Way, while in 
summer we look inward to the denser zones and the core. The MW band in 
summer is brighter and more prominent than that in winter. That's why 
the NYSkies Milky way watch targets only the summer sector of the MW. 
In the two MW watches of 2019 we had no sightings of the MW from the 
City due to poor sky quality. We saw two evening planets, Venus and 
Uranus.Venus is starting to be well noticed after sunset by eye. She 
still is small and mostly fully lighted. Uranus is in Aries, followed 
by binoculars. We noted Vesta in her opposition thru Cetus, Aries, 
Taurus. We learned why we look for asteroids near their opposition. 
They are then closest to us and brightest.They also are in their 
retrograde loop, more a lazy 'S' sweep from their high inclination 
from the ecliptic. We learned that asteroid orbits change 
significantly within a few years. To track asteroids in a planetarium 
or solar system software we need current orbital parameters, like from 
the JPL web. The parameters built into the software are surely 
ediurnate. We correlated Vesta's distance and brightness, seeing how 
she is brightest near opposition and dimmest near superior 
conjunction. We stepped thru example deepsky objects for winter 
observing, most with binoculars. We reminded that Messier did not 
capture all the bright objects. The Rosette cluster in Monoceros is 
one, he missed, yet it is visible by eye from the City on a darker 
clearer night. We admired a couple antique starmaps covering the orion 
region, with Monoceros galloping in the triangle of Betelgeuse, 
Procyon, Sirius. We reminded that wo of autumn's variable stars are 
still in good view in winter, Algol and Mira. Mira is on its decline 
from an October peak brightness but is still easy to find in 
binoculars. a third star, mekbuda is now in high sky. This is an 
uncommon proper name for zeta Geminorum, an delta Cephei variable 
star.  We finished with reminder about current Globe at Night 
campaign, started on Dec 18 and running thru the 27th. takeaways were 
skymaps for winter season, detail map of Winter Hexagon, diagram of 
Milky way galaxy with segments of MW lines of sight, charts of deepsky 
objects in winter sky, finder charts for Uranus and Vesta, current JPL 
orbit elements for Vesta, graphs of Vesta distance and brightness, 
article for winter observing cautions, selection of targets, atlas 
plates for winter, antique atlas plates for Orion area, articles for 
Algol, Mira, Mekbuda.  
    Some 35 local astronomers on Dec 7 did day trip to Franklin 
Institute, Philadelphia PA.. The group was greeted by FI's astronomer 
Dr Derrick Pitts, who explained some exhibits and opened the roofftop
observatory for evening starviewing. They saw 'Museum of the Moon' Moon 
globe, special planetarium show, Apollo-11 IMAX film, besides 
individually exploring the science museum's attractions. Trip was 
arranged by Amat Obsrs Soc and welcomed members of NYSkies, Astro Soc 
of LI, Amat Astro Assn. 
    A few local astronomers joined ~60 artists  on Dec 9 at preview 
of new astronomy-inspired artpieces. The show was at office of creator 
Stellina/Vaonis, of France, on Manhattan during an evening of heavy 
rain. The pieces were built around  Stellina's new line of tabletop 
telescopes fitted with flat video screens. Each piece displayed 
artistic motifs of celestial objects, both static and kinetic. The 
scopes are all-digital imaging instruments controlled by software on a 
smart phone. Wine, canapes, soft music filled the show with cheer. 
    NY Post on Dec 27 had headline 'total eclipse of the sun'. Not for 
the solar eclipse of Dec26, the word was 'son', not 'sun'. It was 
title on ex-US VP Biden's holiday family portrait. Son Hunter, and his 
wife, were left out.

    December was a poorer month for observing with few clear nights. 
Cloud and rain came erraticly, upsetting observing plans. In spite of 
overall adverse weather, The clear nights did yield good views of 
routine targets, even some dimmer DSOs. On the other hand, 
temperatures wee moderate for a winter season, with only a couple sub-
zero-C days. 
    First winter storm of 2019-20 crossed NYSkies on Dec 1, owl hours 
thru late night. Chilly or cold temps, low visibility, blustery wind, 
steady rain or wet snow. Airports closed or airlines cancelled 
flights, road travel was impeded by icing. 
    The national light pollution reward program, TransitChek, 
increases its maximum amount to $270/month on 2020 January 1.It was 
previously $265/mo. Apply at your employee benefit office to update 
your account. Self-employed persons should update thru their 
accountant or legal advisor. In NYSkies some 1-1/2 million people earn 
rewards, totaling around 200 million dollars per month. 
    NYSiers, other observers, scrambled during yearend holidays to 
mount watch on Betelgeuse. Star in fall 2019 began a rapid deep 
fading, beyond its normal fluctuations of brightness. betelgeuse, alp 
Ori, is well up at nightfall and remains in night sky thru April 2020.

    Astronomers on the AOS trip to Franklin Instt on Dec 7 were 
excited by a parhelion dextrum in early morning. They observed from it 
the left windows of their bus on the way to Philadelphia. After 
studying the  apparition for a while they realized it was a horizontal 
contrail that happened to line up with the Sun.
