General News 
 ----------
    Many events in NYSkies were forced out due to four march 2018 
nor'easter storms. Host facilities were closed or short-crewed. Some 
events were formally called off ahead of the storm. Road conditions 
were dangerous. Power lines were cut by blown-down trees or cars 
collision with poles. Rails were blocked by fallen trees or frozen 
switches/signals. 
    Observatory at College of Staten Is in March 2018 closed for 
assorted repairs. It may lose its spring events. I moved it to the 
'???' section. 
    Schommer Obsy, Rutgers U, has three sessions in April, not the 
normal two. They are on April 12, 19, 26.
    Astro Soc of Toms River Area seems to have enduring trouble with 
its events webpage. Altho homepage refers to it, there are no items in 
it. I leave the club in  the '???' section. 
    Natl Musm Math seems to vary the hour for its 'Math encounters' 
show. It's in late afternoon or early eveningm once or twice each 
instance. Inquire at contact for any questions. 
    Astronomers form all over, not only within our turf, are giddy 
wild about ISAW's four-part lecture set of Babylonian astronomy! it 
began on March 28 and continues on April 3,d 4, 11. Almost surely the 
seats are filled by readtime but do get on the waitlist RIGHT NOW. At 
the March 28 talk about 30 guests were on the waitlist and about 20 
were turned away when every last seat was taken. 
    Already you are asking for a book, film, webcast, article, &c 
covering this series. As at issuetitme I don't know of any but I will 
inquire for you. I'll advise you in the Yahoogroup and the email list. 
    NYSkies exhibits at both NEAF and Earth Day this year. NEAF is on 
April 21-22 at SUNY Rockland College, Suffern NY. John Pazmino 
presents talk on 'City of stars' on the 22nd. Earth Day is in Union Sq 
on the 15th. Come visit our booth! 


City News 
 -------
    NYC Mayor deBlasio on 2018 Feb 28 picked Miami-Dade FL school 
director Carvalho to as NYC school chancellor. He would take over from 
Farin~a, stepping down on Mar 31. He suddenly backed out on mar 1 to 
stay in Florida. deBlasio  on Mar 5 went for 2nd choice Houston TX 
school director Caranza, who as at late March is still City's new 
chancellor. 
    In late February 2018 real estate investor Parker Shimn put out 
plan to work around upcoming shutdown of Canarsie subway tunnel under 
East River.r Closure in April 2019 allows repair of hurricane Sandy 
ruin. Plan is a pontoon bridge. L-termatove Bridge, would span river 
from N 7 St & Driggs Av, BK, to Av H * 13 St, MH, with a train of 27m-
long barges. They would be anchored to river bottom and surfaced with 
two bus lanes and two foot/bike lanes. A 5-6 meter clearance under the 
bridge deck passes low boats and a draw bridge near Manhattan end 
passes taller water traffic. Shimn estimates he can build L-ternative 
Bridge in 6-8 months for ~$100 million. Part of cost is recovered by 
$1 toll on foot/bike crossing and a couple dollars for bus riders. 
    A live show on 2018 Mar 9 evening was presented by Dr Neil Tuson, 
Hayden Planetarium. He gave his 'Talk with the stars' show at Brooklyn 
Academy Of Music, where he discussed current topics in space and 
astronomy and then fielded questions from the audience. He gave 
Similar show at King Theater, Flatbush BK, in September 2017. 
    NYSkies Astronomy Seminar on 2 March 2018 explored the spring sky. 
We learned that a large zone of winter stars in early spring is still 
in good view. The generally milder weather in spring lets us observe 
these stars in comfort and convenience. On the other hand, the Milky 
Way also is in the west, receding into twilight during spring. It 
leaves out sky until late spring when the summer segment rises up in 
the east. This shift of Milky Way brings a colLateral shift in deepsky 
objects. Most open clusters are in the west amonG the winter stars. 
Globular clusters are sprinkled over most of the sky. Galaxies fill 
almost the whole spring sky except along the Milky Way. We correlated 
the disposition of deepsky objects with the galactic structure. We saw 
that in spring a segment of the galaxy does not come above the horizon 
in our latitude. We call this the 'Southern Milky Way' but its extent 
varies with latitude. South of about 25d S we can observe the entire 
MW band at some hour and season. The southern MW includes many bright 
clusters and nebulae, favorite targets when visiting south latitude. 
We discussed the rule 'March comes in like a lion and leaves like a 
lamb'. It does, for the American northeast, refer to the change of 
weather from wild winter to mild spring. The choice of lion and lamb 
comes from the stars. In March Leo enters the sky in the east while 
Aries leaves in the west. We joked about the 'lion' part because we 
were at the meeting under a winter storm. For planets we reminded 
about Venus coming into view in March, rising out of strong twilight 
into higher sky in the west after sunset. We reserved detailed 
discussion about Mars until the March 16 session. March is usually 
when the Jewish month of Nisan begins, with Passover under Nisan's 
Full Moon. Historicly this was declared by seeing the first crescent 
after the actual New Moon. Some of us may try to catch sight of the 
crescent soonest after new phase to experience this tradition. i 
mentioned the prospective 'City of stars' walk, run by Amateur 
Observers Society, open for NYSkiers. A test walk is on March 10 
stopping at many all-new astronomy places. AOS will then assemble the 
itinerary for the real tour in late spring. Takeaways were general 
starchart for spring, map of Milky Way with segments labeled, map of 
Southern Miulky Way, table of spring occultations, atlas plates for 
spring zone of celestial sphere, maps of deepsky objects relative to 
Mw, chart of summer MW in owl hours for seeing the MW in May-June, 
scenes illustrating visibility of lunar crescent after new phase. 
    March 2018 was an extra busy month for US Prez Trump. He: 
    * Announced new Jerusalem embassy will open in May, possibly with 
      Israel's 70th anniversary. In January 2018 he noted in the

future modification. 
    FDNY Sgt Davidson was died in fire on 23 March 2018. He was in 
Hamilton Hts MH building when flames or collapse blocked escape and 
his air tank ran out. 
    NYSkies Astronomy Seminar on 16 March 2018 studied the coming 
opposition of Mars. Mars rounds opposition, when he is along side of 
Earth, on 2018 July 27. We played with the geocentric and heliocentric 
model of Mars's orbit, seeing how the two are equivalent in a first 
approximation. We traced Mars's path in spring/summer, watching the 
retrograde loop. All planets go thru retrograde loops but those of 
Mercury and venus occur in stronG twilight or daylight. We examined 
the apparent error of direction for the east/west stations and 
east/west qyadratyre. The 'west' points are in fact west of the Sun; 
'east', east. The confusion comes from missing the circular shape of 
the zodiac; it is not a linear stripe. We saw how the excentric 
ellipse of Mars's orbit cause oppositions of varying separation from 
Earth. The 2018 round is near the Mars perihelion and is a perihelic 
opposition. When Mars is near apohelion, the opposition is an apohelic 
one. We compared disc diameter for several oppositions, seeing how the 
size ranges almost 2:1 between the extremes. The 2018 opposition is in 
Capricornus, a dimmer constellation, about 183 up at culmination. Mars 
is proceding eastward now, in March, thru Sagittarius, visible in owl 
hours in southeast. We studied disc size during this year's apparition 
from west square thru opposition to east square. The largest size last 
only a week or so as Mars zooms past Earth in the retrograde loop. 
Mras was in our sky since fall2017 as a dim pinkish star. His disc was 
far too small for confident inspection in home telescopes. By 
convention we start serious observation of Mars when he falls back to 
90degrees west of the Sun, at west quadrature or square. Observing 
continues thru east quadrature in fall 2018. Mars remains in the sky, 
gradually dimming, thru year end and early 2019. We learned that as 
much as Mars is in the news for space flights and sci-fi adventures, 
the telescope view is a big let-down. Surface texture is weak, even 
when mars is largest, 24 arcseconds at opposition. The best to expect 
in small scopes is a smudge or two and the white polar cap. For this 
year the south cap is tuned to us. This means the  Sun is shining on 
it, in southern spring and summer, and is melting it away. As the 
apparition progresses the cap shrinks. It could be all gone by east 
square. As Mars goes thru his own seasons, with axis tilt of about 25 
degrees, the north and south poles alternate facing toward us. A 
question came up about seasons on Earth. At the equinox day and night 
ar equal but this seems to happen on March 17, not on equinox day the 
20th. Part of the discrepancy is the usual way of citing sunrise and 
sunset. They are the moments the Sun breaks horizon when rising and 
closes horizon when setting. These occur about 1-1/2 off of the 
geometric rise/east when the Sun's center is on the horizon. With this 
correction the equal day/night is on the 20th. An other question came 
about keeping calendars on mars. Can't the Earth calendar be mapped 
onto mars by stretching the months to fill the greater number of mars 
days in one Mars year? Yes, and one diagram in the takeaway had Mars's 
orbit marked in this synthetic calendar. There is no generally agreed 
scheme of calendar for Mars, there being many proposed varieties. We 
cite the date within a Mars year either by a count of days since the 
previous vernal equinox on Mars or the actual longitude of the Sun 
along the Mars ecliptic. As yet there is no Mars chronolgy. Each 
application of timekeeping has its own zero year, like when the 
orbiting spacecraft first turned on its instruments. We were awed at 
learning Mars is the only planet whose physical activity on its 
surface is visible by eye from Earth. When the Mars air is clear the 
planet looks pink or orange from the red sand covering. When a global 
dust storm erupts, usually out of the Hellas basin, a yellow-white 
dust fills th air. The planet from Earth then looks whitish or pale 
yellow. Astrologers considered this color in their work, along with 
the position and motion of the plane6t. We bantered about space 
flights to Mars being that each opposition raises up a bunch sent 
there. They launch 2-3 month before opposition and arrive at mars a 
few months after opposition. The timing takes advantage of proximity 
to save travel time and fuel. We noted that on the way to mars the 
spacecraft follows a solar orbit in free fall. The optimum path was 
worked up by Hohmann in the 1910s as part of the effort to build a 
spacefaring industry in the early 20th century. A bonus at this 
meeting was six tickets for American Museum. They give free admission 
and one free extra show during the visit. Several NYSkierss took them 
home.  A late-breaking bonus was an alert about Tiangong-1, China's 
fist space station. Radio comms were broken in 2016, leaving it in an 
uncontrolled orbit. The orbit is decaying from air drag with a fall to 
Earth expected in late March to early April.  The final prediction 
will come only in the last several orbits, about 6 hours before fall. 
Satellite observing webs will carry latest news. Takeaways were map of 
Mars retrograde loop, helioocentric and geocentric model of Mars, 
orbit diagrams for oppositions, pictures of Mars disc size during this 
opposition and compared with others, general planet elongation chart 
for 2018, articles on observing Mars, maps of Mars surface for small 
scopes, world map of Mars. 
    Physicist & cosmologist Stephen Hawking passed away on 13 March 
2018 at his UK home at age 76. he was overtaken by long-time ALS or 
Lou Gehrig's disease, that hit him at age 21.  Hawking developed 
blackhole theory and tried to discover a 'theory of everything' for 
all of physics. In his last years he suggested there may be no union 
for quantum and Einstein physics, nor any way to unveil the mystery of 
a 'god'. His books, TV shows, movies enlightened both home astronomers 
and public, like 'A brief history of time'. He also appeared as cameos 
or 'walk-in', with his motorized cart, parts in other films about 
science. 
    John Pazmino and Steve Kaye were among ~400 judges at NYC Sicence 
and Engineering fair on 2018 March 4. The Fair was at City College, 
Hamilton Hts MH with some 500 high school student presenting their 
science projects. The projects they inspected were well prepared  and 
presented, earned good scores.By an imbalance of projects categories 
and judges, Steve and John were each  assigned only a couple projects, 
down from the usual 5 or 6. 
    A chartered helicopter crashed in East Rv on 2018 March 11 ~19:15 
EDST. It took off from Wall St, heading north, and went down off 88th 
St with apparent engine failure. The craft landed upright but suddenly 
flipped over and sank. The pilot escaped but could not free his five 
passengers strapped in their seats under water. All died at scene or 
in hospitals. Police towed craft, a AS350 model from Liberty 
Helicopter, to shore where at end March it was under study. 

Sky News

    NYSkiers were pumped up for possible aurorae on 2018 Mar 7 & 8. 
Massive solar eruption several days earlier would arrive at Earth but 
time and place of particle iinflux were uncertain. Both nights in 
NYSkies were too cloudy for aurora watching and most Globe at Night 
assessments were 'none'. 
    As at 29 March 2018 China's Tiangong-1 space station is still in a 
rapidly decaying orbit. Launched in 2011, all control of it was lost 
in 2016. It was since in a freefall path under air drag. The 10m, 9ton 
craft could drop down on April 1st and may have done so at readtime. 
If the drop is over NYSkies at night  in clear sky you'll see a 
humongous spray of meteors  
    Daylight Savings Time on 2018 March 11 came this year to NYSkies  
on the sneak, with little notice in news media. Normally the media 
remind the public on previous day to move clocks ahead for EDST. Lack 
of strong reminders made many people miss the clock change until well 
within March 11. March is the 2nd month in 2018 with a 'blue Moon'. 
This is according to the soft rule of being the second Full Moon in a 
calendar month. The Full Moons of March are on the 1st and 31st. The 
latter is also the Passover Moon . 
    Four nor'easter winter storms blew thru NYSkies in March 2018. 
They sweeped over on 1-2, -/, 13-15, and 20-22, hitting different 
section of our territory to dump heavy snow, dense rain, strong wind. 
Roads covered in ice and slush, rails  blocked by downed trees or 
slowed by damaged signals. Widespread electric cuts when power lines 
were ripped down by falling trees or collisions with poles. The storms 
forced cancellation of many activities, including schools and shows. 
    More observers are seeing Venus, low in west-southwest within 
half-hour after sunset. My own first view was on March 8, 2018, 
skimming skyline. She could be missed as a distant street or yard 
light. Venus creeps farther from Sun and higher over skyline in April. 
Later sunset due to DST will help those who until now get to their 
viewing site too late on the clock. 
    Ultra clear night over New York City on 2018 March 16. NYSkiers 
arriving home from Seminar, other astronomers under the sky, saw the 
fainter spring constellations. Among them were Hydra, Corvus, Cancer, 
Monoceros, Ursa Major, Lynx. Transparency was 4-1/2 to 5th magnitude 
generally over City. Some observers spotted Beehive and Coma clusters. 
My own Globe at Night measurement was 5th magnitude, with Orion 
getting low in west. 
    By March 17, 2018, most astronomers in NYSkies got first sight of 
Venus in this year's apparition. The sky was clear and dark, not quite 
so dark as on the 16th but thoroly one of the better nights. Some 
spotted her while trying to catch First Crescent  for jewish month of 
Nisan. March 17 was in fact Nisan 1. 
    Globe at night readings in Earth Hour on 24 March 2018, 20:30-
21:30 EDST, were hindered by clouds and gibbous Moon. Observers 
reported no obvious reduction of luminous graffiti during the hour.
