General News
----------
NYSkies shifted its first July Seminar from the normal first
Friday to the second. This sips over the long 4th of July weekend. We
meet on the 12th, then, by our regular schedule, the 19th. Both
sessions celebrate the Apollo-11 th anniversary with films and slides
for the 1960ss-1970s and, uh, 1890s-1900s.
July 2019 is the 50th anniversary of the Apollo-11 landing on the
Moon. While some astronomy and space centers announced commemorations
this event many as at issue date did not. Plans could be put out in
early July or even shorter notice.Inquire at your local center for its
apollo-11 events.
Curtailed service on Canarsie line affects both Manhattan and
Brooklyn. trains within Manhattan run on only one track spaced about
20 minutes apart. I rewrote the entry for this event and duplicated it
for both boros.
I moved the entry for the measles epidemic to 'ongoing and
continuing events'. This situation could be a long-lasting one for
several years.
The annual Parade of Trains, normally in June, for 2019 is running
on September 28-29. The Transit Museum rolls out some of its historic
trains for public ride on the Brighton Line. Details in due course.
Several events in the '???' section are moved to the 'AUT'
section. I allow that they are in recess for the summer. If any
resumes early, I'll list it under its proper date. Please note that
seasonal events may resume at a different time and place from the
preceding season.
Intrepid Museum now offers monthly 'Free friday' evenings thru
October. The July one is on the 19th. The entire Museum is open, pier
and ship, with occasional extra clearsky outdoor movies and
starviewing.

City News
-------
A private helicopter crashed onto roof of 787 7th Av on June 10
~13:43 EDST. It dropped off rider at 34th St heliport and was flying
back to base in Linden NJ. Pilot, Tim McCormack, lost his way in
thick fog and apparently tried to land on roof. He was killed and
craft was totaled at impact. A small fire broke out on the roof, put
out by FDNY. US FAA and NYPD are investigating.
NYC Transit's new OMNY fare payment system started on May 31 along
Lexington Av line, Grand Central to Barclays Ctr, and on buses on SI.
There were many glitches when the sensor didn't sense the payment
device or rang up fare without releasing turnstile. With lower traffic
on weekend of June 1-2, NYC Transit was troubleshooting the problems.
NYSkies Astronomy Seminar on June 7 examined the summer sky and
Milky Way. We compared the summer alignment of Milky Way in sky with
spring when it was low around the horizon. The summer sky is dominated
by the Summer Triangle and Scorpius-Sagittarius. The third region,
dimmer and sometimes under-explored, is occupied by Draco, Hercules,
Ophiuchus. Altho their stars are dim, they contain lots of interesting
targets for city astronomers. The MW is in high east and south for
summer with its open and globular clusters. Open clusters hug the MW
path horizon to horizon. Globular clusters are thinly scattered all
over and concentrated toward the galactic center. In our latitude the
GC is low in south, tempered by thicker air, ut there are many
globular clusters accessible in binoculars and small scopes. Also in
the summer sky are several brighter nebulae, a target usually
smothered by the gray sky over the City. These are both open nebulae,
amorphous clouds of dust/gas, and globular nebulae, gaseous shells
from star outburst. We studied a general skymap to see how the stars
of spring are moving westward into evening twilight and the autumn
stars are rising in the east. Er teminded that it's common to study
the stars of the next season by waiting several hours, into the owl
hours, to let these stars rotate into the south. Astronomers do this
specially in spring and fall, when weather is cool and comfortable.
Summer is in our part of the US often torrid, humid, and infested by
insects. By same reasoning, watching the winter stars in autumn avoid
the winter evenings of frigid windy air.We looked at asterisms among
the summer stars, mainly associated with the Summer Triangle and Sco-
sgr. The Triangle is the largest asterism anchored by stars Vega,
Altair, /Deneb. Smaller ones unlude downtown Delphinus, Sagitta, Lyra.
Other small asterisms are the Caput, Head, of Caprocornus, Cerberus,
Draco, Aquila. Downtown Sagittarius is a drop-dead teapot. We traced
its handle, spout, lid, &c and even a lemon, teaspoons, and steam
among the stars. Scorpius for our latitude is sometimes treated in two
parts, the western is the head and heart of the scorpion and the tail
and stinger is the eastern part.We got no bright comets in summer, and
no bright asteroids. We also have no really interesting occultations.
We examined one that at first looked good to observe, a daytime
occultation of Venus. Daytime occultations of planets are
fascinating events, so we took a closer look at this one, on July 31.
We found by simulation in a planetarium software that this event takes
place only a few degrees west of the Sun and is beyond feasible
observation. This was an example of how to catch false alarms in
future celestial events. We discussed the new 'train in the sky'
Starlink satellites. These 60 sats were orbited o may 23 by spaceX as
the initial set of some 12,000 by mid 2020s. The brigade is near
threshold for city observers by eye but is easily followed in
binoculars. In a month or so, details still wanting, SpaceX will
disperse the sats into final service orbits, like at train dropping of
its wagons onto branch tracks. To know when and where to watch for
Starlink, we looked at one satellite tracking web, Heavens-above. We
de hoe yo set it up for the observing site.The web address is modified
to include this location and is immediately bookmarked. To use H-A in
the future we open the bookmarked address, not the raw web address.
Many interesting satellites are listed in H-A with Starlink as a new
entry. Picking Starlink, or any other satellite, yields a timetable of
passes over the observing site for the next week. We stepped thru the
columns in the timetable and looked at the starmap with the passage
marked on it. This is obtained by clocking on a desired passage entry
in the timetable We saw that the observing location has to be set
within a few kilometers to minimize perspective or parallax deviation.
Within New York City H=A includes many large districts, for better
geographic resolution. We learned that satellites are in dynamicly
evolving orbits that can not be reliably predicted far into the
future. Satellites in low orbit, and visible in the sky, are
influenced by air drag and Earth's bumpy gravity field. Higher sats
are pushed and pulled by the Moon and solar radiation pressure. A
prediction made a ew weeks ahead is be all wrong. Starlink has an
additional hazard for future predictions. The sats have ion drives
that will be turned on at will to shift orbit. A prediction generated
before the thruster action is exfenestrate. We got two night planets
Jupiter and Saturn, to be explored at the June 21 meeting. The two
planets are now closing together to pass each other in late 2020.
Normally we take up Jupiter and Saturn in separate session because
they are far apart in the zodiac. Starting in 2019 into 2021 they are
close enough to enter our sky in the same month. We now examine both
planets in one session. Takeaways were starcharts of the summer sky,
diagram of asterisms, maps of Milky Wa and associated targets, chart
of Jupiter & Saturn paths, summer observing article scene of Venus
occultation, sample pages from Heavens-above, atlas plates covering
summer sky, sample historical starmaps with the mythical characters.
NYC Mayor deBlasio on June 12 won a seat at the Democrat president
candidate denate, set for June 26-27. He's in the first day's round
with 9 other candidates. 10 more are seated in the second day. Four
hopefuls missed a seat from shortfall of campaign donations or
endorsements.
The History Channel on cable TV began on May 31 10PM EDST a series
about modern UFO activity over US. Show included US Navy report of
UNDERWATER flying saucer in Atlantic Ocean and apparent spy saucers in
Pacific airspace. Check own cable schedule.
Small tornado in New Jersey during mass rainstorm on 28 May
~20:30 EDST. It touched down in Morris and Sussex counties, tore down
trees and power lines, damaged structures by wind-blown wreckage.
Tornado bumped Lenape HS, Stanhope NJ, ripping fixtures and
fittings, yet leaving unharmed attendees of a banquet inside. No other
injuries or deaths reported, only widespread light damage along
tornado path.
NYSkies Astronomy Seminar on 21 June was one of the busiest in
recent years, examining both Jupiter and Saturn. We welcomed two new
attendees Susan and Vira. We first explored the planets and their
moons, detailing the planet structure and moon orbits. Altho Saturn is
the most beautiful planet, Jupiter is the most dynamic one. Saturn
presents about the same aspect all thru a given apparition. Jupiter
shows agitation in his clouds, varying activity in the Great Red Spot,
and dance of his four large moons. All during the meeting Joe Fedrick
added fascinating comments on their observation of the planets by eye
and telescope. The moons were first seen by Marius in England, who did
't publish his observations. They were found in his effects long after
his death He named the moons as we now know them. Galileo published
his observations but only numbered the moons I thru IV. The sequence
es soon adjusted from neatest to Jupiter to farthest. The names were
first popularized by space explorations in the 1970s and are in
universal use today. Newer moons are numbered as discovered and given
names from Jupiter's mythical family. Saturn's largest and easiest
seen Moon is Titan, and four/five others are discernible in larger
telescopes. The rings are lettered A to C outer to inner, with C the
crepe or gauze ring seen in larger scopes. a and B are divided by a
gap, Cassini's division. Crude optics and tilting ring confused early
observers about the planet's structure. Huygens in mid 1600s figured
out the planet was surrounded by a thin flat ring. The ring tilt is
caused by viewpoint from Earth as Saturn orbits the Sun. The full
cycle of north open, edgeon, south open, edgeon, and back is one
Saturn year of 29-1/2 Earth years. Older members at the Seminar recall
seeing Saturn thru two of his years and Jupiter thru five of his, each
being 12 Earth years. Jupiter has almost upright in his orbit with
equator facing us. We do not see the polar areas well and the Moons
see-saw back and forth around him. Galileo recognized Jupiter as an
other center of revolution besides only Earth, evidence tho not proof
that Earth could revolve around the Sun. Jupiter's moon move rapidly,
showing definite motion within a few hours. They also pass ahead or
behind the planet, throw shadows on it, and pass thru its own shadow.
Tales in Jupiter observing litterature list these vents. They were
tried as a way to find longitude by timing the event in a ship's local
clock and comparing it to the calculated time for the home port. the
method failed from difficulty of handling clumsy telescopes on a ship
at sea. We discussed Juno, spacecraft at Jupiter. We studied diagrams
of its flight from Earth and the settlement into orbit at Jupiter. We
learned the craft uses solar panels because when planned there was too
little plutonium in stock for the nuclear power supply. We looked at
the movement of Jupiter and Saturn in the past few and future years.
Jupiter gains on Saturn, being now one zodiac sign behind, west, of
him. In winter 2020 the two pass so closely that they look like a
brilliant double star. The two fit in a low power telescope field.
Then after the two separate with Jupiter pulling ahead. Such
conjunction occur every 20 years. Older astronomers at the meeting
recall seeing one or two previous ones. We had side dialog about
computer software with members showing astronomy programs on their
phones or tablets. We also explored astrology programs to demonstrate
planet motion in addition to position. They show dramaticly the
retrograde loop of Jupiter on a speed-position chart. Astrology
software also finds desired celestial events, like Jupiter- Saturn
conjunctions. One diagram presented a table of these conjunctions from
1950 to 2025 and a graphic timeline. Takeaways were pictures of
Jupiter and Saturn, orbits of their moons, position and motion in sky,
sample Jupiter moon events, historical diagrams of Saturn rings,
changes in Great Red Spot, size comparison of planets and Jup/Sat
moons, digarms f Jupiter moon positions and events, angular extent of
Jup moo orbits in sky, Juno flight path, digrams of Jup-Sat
conjunctions, simulated telescope view of 2020 conjunction. We ran
quite up to 21:30. We ere finishing the last bit of dialog as the
building crew came in to close up shop.
Nik and Lijana Wallenda staged awesome tightrope walk across Times
Sq on June 23! The rope stretched from 1TS (Times Tower) to 2TS, 390m
long, 25 floors above street. Nik started at ~21:15 EDST from 2TS;
Lijana, 1TS. They crossed together mid way and continued to opposite
end. Nik finished first, ran [on street] to 2TS to greet Lijana as she
stepped off rope. Walk took ~38 minutes with no visible problems.
Several hundred thousand spectators filled the Square, myriads more
packed adjacent office towers. Weather was day, calm, warm.
On June 17 Penn Station began work on new entrance for LIRR at 7th
Av & 33rd St. It leads into the existing LIRR concourse, itself to be
rebuilt. The astronomy artifact 'Eclipsed time' could be removed.
Altho it broke soon after unveiling in the then-new concourse i 1990s,
ir is the first stop on the 'City of stars' walking tour.

Sy News
-----
Weather in June was a crazy-quilt of awful rain and cloud with
brilliant sky. A night could start with rain, then clear up
wonderfully in owl or predawn hours. or vice verse, first dazzling
clear, turning to cloud and storm after midnight. Pattern irritated
astronomers, overturning planned observing.While there were no Milky
Way reports, observers enjoyed skies filled with tiny stars decorating
the downtowns of summer constellations. Deepsky targets were textured
and more easily found.
Strong hail storm hit NYC in late afternoon of June 2. Lasted only
ten minutes as it raced W-E over City, but hail stones were a cm or
two diameter.
Observers have thrill and threat from new Starlink brigade of
satellites cruising thru the stars. Orbited on May 23 by SpaceX to
start a new global grid of hi-speed Internet, it has 60 small sats in
a 60ish km long line. Each is 4-6 magnitude, with some passes of 2-3
magn. Train is 5 or so degrees long and takes a few minutes to cross
the sky.
Scattered sightings of rainbows on 20 June late afternoon. Very
spotty due to patchy rains all day. Most rainbows seen within hour
before sunset, when bows were elevated above local skyline.
Manhattanhenge was mostly lost to clouds and rain on May 29-31. A
couple observers got a glimpse of the setting Sun thru cloud breaks on
the horizon, while rain threatened overhead. Next Manhattanhenge is
July 9-11. We hope to watch it at its final view at our July 12th
Seminar.
Possible Milky Way sighting reported in owl hours of May 31,
following dense rain in preceding evening. sky was dazzling with lots
of faint stars along Milky Way path and in the dimmer constellations.
Uncertain sighting of M24, Lagoon nebula, Scutum cloud. Most reports
were spinoff of observing Jupiter and Saturn and came from E BC, S BK,
S QN, E SI.
The next leapsecond is added at end of June 30, 23:59:59 UT,
19:59:59 EDST. The time sequence is

..., 19:59:58, 19:59:59, 19:59:60, 20:00:00, 20:00:01, ...

This event can be watched on devices gagned to a global time service
and displaying seconds. Stand-alone and mechanical clocks will not
show the leapsecond.
