general news
 ----------
    Several August events in north New Jersey were cancelled by massive 
rain and flooding. Most seem to be forced out of action due to the 
quickly rising waters and short leadtime of hazard notices. Roads and 
rail were blocked by downed trees and floating vehicles. 
    Science & the Arts leaves NYC Events. It seems dormant with 
ediurnate web and no recent events. If it revives I'll welcome it 
back. 
    Westchester Amat Astro now meets in Lienhard Hall of Pace 
University. Previously it convened in Miller Hall. it also posted its 
2018-2019 dates for its monthly members meetings. 
    Simons Foundation is up and running after the stram explosion on 
its street corner. it in late August posted a full slate of lecturees 
for fall 2018. See Sep 12. 
     I list the annual .meeting of the UN General Assembly, 2018 Sep 
25-Oct 6.  No, you can not participate in the GA sessions! There may 
be collateral public events at the UN on short notice in this time 
span. There is an increase in public activity at the UN in 2018, with 
several NYSiers taking in a one or an other. As i learn of them, I'll 
post them into our yahoogroup. See Sep 25. 
    Summer Streets, on 2018 Aug 4, 11, 18, suffered oppressive heat or 
massive rain.  The Park Av tunnel was closed with no walk-thru this 
year. 
    I simplified the entries for Vassar Coll  and Wesleyan Univ 
observatory public nights. These are on Wednesdays only when classes 
are in session. Over the years it got more ambiguous to interpret the 
schools's academic calendars. This caused NYC Events to miss sessions 
or list a skipped one. Please inquire at the contact for each instance 
of a visit. 
    I'm always proud when you great astronomers come to our Seminars. 
But I do remind that we meet TWICE per month, NOT 'every other 
Friday'. August had five Fridays: 3, 17, 31. The Seminar was on the 
3rd and 17th ONLY. There was NO Seminar on the 31st. 

City news
 ------- 
    A tornado sliced thru College Pt and Whitestone, QN, on 2018 Aug 2 
22:20 EDST. It touched down during a strong thunderstorm, travelling 
west for ~1200m, then dissipated before reaching Whiteston Bridge.  Of 
strength FF-0, it scored a 100m path, ripping up trees, bruising 
homes, tossing cars. No reported injuries or deaths. 
    Three men were hit by lightning during a thunderstorm on 7 August 
2018. Two were playing soccer in Flushing Meadow-Corona Pk, QN, at 
~19;30 EDST when both were felled by a bolt and were treated at 
Elmhurst Hospital.At ~19:55 the third man was struck while tending to 
his car at 155 St & Baisley Bv, Jamaica QN. He was taken to Jamaica 
hospital. All three, tho seriously injured, are expected to survive. 
    NYSkies Astronomy Seminar on 2018 august 3 prepared us for the 
Perseid meteors, peaking on August 12-13 this year. We first discussed 
the raging storm on mars that by mid July completely blanketed the 
planet. Storms commonly occur as mars rounds opposition, suggesting to 
19-20th century astronomers that the people up there were deliberately 
hiding from our view. Clouds and rain interfered with observing mars, 
but on the occasional clear night the planet was more white than red. 
This is reflection from the light-colored dust screening the darker 
red surface. The Perseids are a streamtube of meteors sprinkled around 
the orbit of comet Swift-Tuttle. Its orbit passes close to Earth's 
intercepting on the same date each year, August 10-13. Earth pulls in 
some of the comet debris. As the particles fall thru the atmosphere, 
they heatr into incandescence. The grains makes a steak in the sky as 
the very meteor. The material of Swift-Tuttle is evenly spread all 
around its orbit. Each year Earth is sure to catch a good sample and 
produce a satisfying meteor shower. This is contrasted with the 
Leonids of November. Its comet, Tempel-Tuttle, maintains its debris in 
a clump that circles the Sun in 33 years. Earth catches this clump 
only every 33 years, with several near misses with no meteor shower. 
The first to recognize that August had the most shooting star activity 
in the year was Quetelet, a French health official in the 1830s. In 
his job he invented the discipline of social statistics and the mass-
height measure of human body build. A few years later several teams of 
observers, recruited from home astronomers of the era, standed vigil 
in August to better document the meteors. They found the most shooting 
stars seemed to radiate from Perseus during August 10-13. Over the 
next decades, until the discovery of the meteor-comet connection in 
the 1860s, the August, and November, shooting stars were a major 
curiosity  of the heavens, even among the public. The debris flows in 
parallel paths along the comet orbit and we see the meteors by looking 
upstream into the flow. Perspective makes it seem that the meteors 
radiate from a point among the stars, like the convergence of parallel 
lines on Earth, such as railroad tracks. or several decades the two 
showers were simply the August and November meteors. As more showers 
were identified, the practice arose to name them after the 
constellation of their radiant. since the constellation produce the 
meteors as offspring, the name is the patronymic of the constellation: 
leonids and Perseids. We examined the moonskip effect that this year 
gives us a new Moon during the Perseids. In other years the Moon may 
be in large phase in the sky to hinder observing of the shower. This 
moonskip feature can be used to plan attendance at outdoor events 
occurring on the same calendar date each year, like a the July 4th 
fireworks show. We saw the the effect derives from the 'rule-of-19'. 
We recalled previous displays, for the most part good ones, seen from 
various vacation or weekend getaway from the City. Meteor showers 
suffer badly from luminous graffiti by veiling the numerous dimmer 
shooting stars that make the shower effect. Only the occasional bright 
meteors show thru. We studied diagrams of comet swift-Tuttle to learn 
that usually only one crossing of Earth's orbit for a comet. The other 
crossing is some far distance from Earth and produces no meteors. 
halley's comet is special for having both orbit crossings near Earth. 
The south-to-north one is in May to produce the Aquarids. The north-
to-south one gives the Orionidsin october. We had dialog about the 
strength of a shower, in meteors per hour. The book value, 60-70 for 
the Perseids, assumes an all-sky view, radiant in the zenith, and 
sky transparency of 6th magnitude. These conditions are hardly ever 
realized for a typical observer. The achieved rate can be half or less 
of the book rate. We saw how the altitude of the radiant influences 
the display. The radiant must be in high sky, limited by dawn, to let 
the shooting stars fall down onto the observer. A low radiant sends 
meteors skimming across the atmosphere, most missing it, with only a 
few falling as shooting stars. To watch the Perseids, Perseus must be 
in high sky, occurring from about 2AM thru dawn. Comfort is every 
thing in meteor shower watching. a lawn or deck chair is lined with 
soft blankets. Soft drinks, juice, chewies are close to hand. Light & 
easy music soothes the mind and eye. We explained that meteorites in 
mmusea are mostly made of iron because they are the easiest to 
recognize among earthly rocks and stones. Shower meteors are almost 
entirely rocky, not iron, Comets theselfs are porous rocks that spew 
out grains of dirt that eventually fall as meteors. Iron meteorites 
apparently come from stray bits of iron asteroids in the main Belt.

    Service on Sea Bh line was interrupted on 20 August 2018 by two 
goats wandering on its tracks. They were first reported at ~12:30 EDST 
between Ft Hamilton Py and New Utrecht Av stations and were captured 
by transit workers at 13;10. The goats probably escaped from a nearby 
slaughter yard but Jon & Tracey Stewart, of 'Daily Show' fame, took 
them to an animal sanctuary in watkins Glen NY. 
    Two apartments in One East River Place, 72 St & FDR Drm< MH, were 
hit by rifle shots. A resident on the 14th floor woke up on 2018 Aug 
17 to find a wondow shattered and recovered a bullet. On the 18th 
~01:15 EDST a resident on the 32nd floor was awakened up smashing 
noise and found a window broken open. Police tracing the shots and 
reviewing security videos determined the gunner weas on Rossevelt Is, 
some 500m away. No arrests as at issue time.  
        NYSkies Astronomy Seminar on 17 August 2018 was for presenting 
reports of the mars dust storm and Perseids. Mars was smothered by 
summer haze and some California forest smoke. The Perseids were 
totally rained or clouded out over NYSkies. he main topic was the 
exploration of the Moon's motions around Earth. We looked at the stock 
picture of lunar phases and extracted several more features from it. 
To aid in better seeing the phase we explained the ball trick and 
pocket monocular. Hold a small rough-texture ball, like a tennis or 
Spalding, next to the Moon near sunset.the low Sun must shine on the 
ball, in open sky. The phase on the ball is the same as on the Moon. 
The monocular i showed is a Russian import from the former USSR's KGB. 
it fits in the palm and has 3X power. It's handy for sightseeing, 
reading distant signs, checking out asterisms, and, yes, assessing 
the lunar phase. The phase of the Moon is tied to the time elapsed and 
angular run since the last new Moon. In some cultures the Moon is a 
all-new creature in each cycle of phases. Her age is the lifespan age 
until day 29 when she dies just before the next new Moon. We also saw 
that the phase relates to the diurnal hours displacement from the Sun 
as a means of telling time at night. We learned that the Moon is so 
close to us that our sightline to her swings some 2 degrees over the 
Earth's globe. This displacement in the sky affects eclipses and 
occultations, causing them to favor certain observers and missing 
others. The Greeks measured the Moon's perspective swing, parallax, 
that the Moon's orbit is quite 60 times the diameter of Earth. We 
studied charts of the Moon's parallactic displacement during an 
occultation of the Pleiades and the track of an occulted star observed 
from various towns. We demonstrated how to tell time  by the Moon! 
First we must know the compass directions around you, specially south. 
Then pretend the Moon is the Sun and assess the time by her 
displacement from the south meridian. Then add to this raw time the 
hour offset from the chart in the takeaway, according as her phase. 
For a rougher time, clues come from the location and phases of the 
Moon in the sky. A crescent Moon in evening is in the western sky when 
low. A large Moon when low is in the easter sky. We saw the effect of 
the lunar orbit inclination of 5-1/2 degrees. The Moon passes thru the 
zodiac over a slightly different path each month, repeating over a 
19ur cycle. Occultations come in 'seasons' 19 years apart as the 
Moon's orbit brings the Moon over the star or away from it. We noted 
that the Moon moves 1/2 deg/hr thr u the zodiac, while carried 15 
deg/jr west by daily sky rotation. On the Moon this amounts to quite i 
km per sec. This is about the speed of the lunar shadow on the ground 
in a solar eclipse. Some of us recalled their sight of the shadow in 
the August 2018 eclipse. We welcomed two new guests: Joe Fedrick 
and Davida se la Cruz. Joe is a NYSkies correspondent but didn't 
recently come to the Seminar. He discussed the dust storm on Mars, 
which he tries to follow under the City's adverse weather, and his 
experience at the August 2018 eclipse. Davida is new to astronomy, 
et added good questions about the Moon's movement and helped answer an 
other about speed of meteors and Earth. Takeaways were diagrams of 
lunar phases, photo of earthsine, monthly and yearly calendar of Moon 
phases, maps of lunar orbit and path thru zodiac, sky charts of Moon's 
seasonal change of path thru the sky, chart of hour offset for lunar 
time-telling and visibility during the night, chart of parallax 
displacement of Moon during occultation, chart of selenehelion. The 
previous instance was the lunar eclipse of January 31, 2018, when the 
Sun rose while Moon was sinking into umbra.

    The NYSkies Observer's Handbook offer opens in mid September. 
The cost per copy is still $23, with pack & post to you. In the past 
we discouraged 'anticipation requests' because there was the prospect 
of a price increase from the previous year. Since the cost is stable 
for this 2019 edition, you may, if you want, send in your request now, 
before the formal opening of the offer. See September 16. 
    August was an awful month for observing with few good nights. 
Almost all nights were covered by clouds or filled with rain. The days 
were torrid and humid with temps in the mid to high 30Cs. 
    The Perseids were rained or clouded out all over NYSkies. The nest 
report so far was David Teich's sighting of two  extra brilliant 
Perseids thru thick haze. He watched from a Hudson River pier near 
70th St, where he was a couple hundred meters from shore with an open 
sky. He noted he could see no other stars and had to eyeball the 
location of Perseus. 
     The annual Tribute in Light on September 11th is a Tuesday. The 
twin beams from the PA parking garage just south of the WTC turn on in 
late twilight and shine until dawn of the 12th. Do try to measure their 
height, to the top of the visible beam, even if capped by clouds. You 
need the ground distance from observing site to Rector & West St and 
the altitude of the bean top. full instruction are at 

    www.nyskies.org/articles/pazmino/trib-lt.htm

In past years, in clear sky, the beams reached to tens of kilometers 
high.
    Observers are giddy about the dust storm on Mars, 
bare-eye and binocular efforts were upended by the dense haze on clear 
nights. It tinted everything red or orange, masking the real color of 
Mars with its tunic of dust. Steve Kaye, as example, on August 12 and 
13 was fooled by a bright orange star in the west in dusk. He was 
amazed to realize it was Venus, normally candid white.
    Steve Kaye on 17 August 2018 noted that some smoke from the 
California forest fires drifted to the East Coast. It apparently adds 
to the local summer haze to color celestial objects red. Joe Fedrick 
recalled that some 20 years ago forest fires in Canada sent plumes of 
eye-stinging smoke over the East Coast. Observing during the incident 
was smothered. 
    The dust storm om Mars may be waning by mid August. Scattered 
telescopic reports tell of threshold visibility of the darker maria. 
Joe Fedrick on August 16 discerned Syrtis Major while i previous weeks 
the planet was thoroly blank. On the couple clear nights in the 20s of 
august I by eye saw Mars as still white. 
    Venus in mid August rounded her dichotomy, half-moon phase, and is 
racing toward inferior conjunction. In September she rapidly swells in 
angular size and shrinks in phase to a large thin crescent. Binoculars 
can follow her all the way into evening twilight into October.
