We are cancelling Sidewalk Astronomy in Monrovia tonight. If you do get
a clearing, here is a star chart for 5:30 p.m. Pacific Standard Time
tonight.https://goo.gl/ROgrsB
You could break out the binoculars and try looking at Venus and Mars and
the moon. Between the two planets is fainter Neptune. If you can see
below Venus you canalso try for Comet 45P for about an hour after
sunset, depending on your location andif you have a flat SW horizon.
Neptune is blue, comet is needle-shaped with the tail pointing up as it
is being blown by the solar wind!
We'll have news about our next Mojave National Preserve Star Party
(possibly April or May), next sidewalk astronomy night, future
Huntington Garden star party, and the Solar Eclipse next time. We now
have about 4 folks from our sidewalk Astronomy family joining us at the
Idaho Dunes RV Park. Toggle between the map, and the reservations pages
https://www.idahodunesrv.com/map.php and
https://www.idahodunesrv.com/reservations.php?month=August+2017 We are
in spaces 50-56, and you can several nearby spaces available.
Speaking of the Eclipse, NASA's Lunar Reconaissance Orbiter LRO

My two astro products (for my work at JPL) are What's Up and a new thing
called Ten Things. It's a list of ten interesting things happening in
the solar system each week. I sneak in a stargazing "thing" almost every
week, and this one features all the 2017 Meteor showers, so it's a
useful bookmark. :-)

Hi everyone and welcome new members from the Mojave National Preserve
star party last weekend! We are already setting up the spring date
which we'll announce once its finalized. There were over 50 tents, over
120 attendees, a couple dozen attendees were urban youth, visiting MNP
and camping out for probably the first time looking through about 10
telescopes! Article and photos
http://www.mojavepreserve.org/news/2016/11/7/promoting-the-preserve
We were expecting a lot of questions about the "Supermoon" at the
telescopes tonight, but it's super cloudy, so we are cancelling our
sidewalk astronomy -- we usually hold it near the first quarter moon
Saturday night, but we did Mojave non that night this month since the
campground was available. Both Sunday and Monday night will be about
equally good to measure the "full " or what we astronomers call a
"perigee" moon, so look in binos
In a nutshell a supermoon new or full moon which occurs with the Moon at
or near (within 90% of) its closest approach to Earth in a given orbit.
Dubbed so by an astrologer in 2011. Because the Moon's orbit is an
ellipse instead of a circle, its distance from Earth varies during the
month from about 225,800 miles (363,400 km) at perigee, or closest
approach, to 252,000 miles (405,550 km) at apogee or furthest distance
in the elliptical orbit. Changing the distance causes the Moon's size
and brightness to change as well. A perigee moon is on average 7% bigger
and 16% brighter than an average full Moon, but during an unusually
close perigee (the supermoon moon), the full Moon can be 12–14% larger
than a full Moon at apogee (farthest) and 30% brighter. There are nice
graphics and explanations here -->
http://www.skyandtelescope.com/observing/see-the-biggest-supermoon-in-68-ye…
If it is clear tomorrow, the full moon rises at 4:38 p.m. here in
California. The moon turns precisely full on November 14, 2016 at 1352
UTC <http://earthsky.org/astronomy-essentials/universal-time>. meaning
the moon will reach the crest of its full phase on November 14 at 1352
UTC <http://earthsky.org/astronomy-essentials/universal-time>. That
translates to 9:52 a.m. AST, 8:52 a.m. EST, 7:52 a.m. CST, 6:52 a.m.
MST, 5:52 a.m. PST. The moon will reach perigee – the moon’s closest
point to Earth for this month – within an one and one-half hours of that
time. This EarthSky article gives a lot of other great information and
graphics! http://earthsky.org/?p=190918
There are 4-6 supermoons every year, so have a look, and do what I am
going to do -- make a moon measuring device and start comparing! All you
need is an index card shown in the Sky and Telescope magazine article
above, with some 5 mm to 10 mm slots cut unto it. 6mm is close to 1/4
inch, fyi. Hold your moon measurer straight out, aim at the moon, and
see which slot matches the moon's diameter, write down the date, repeat
next full moon. You can also hold your index finger out stretched, and
see that it covers both regular full moons, closest perigee moons, as
well as farthest away moons. :-) Some astronomers hate the name
Supermoon, but if it raises awareness, I'm good with it. :-)

What's Up November 2016:
Venus, Jupiter and Saturn + more meteor showers
https://youtu.be/aj7hDvy9bgI
Although my JPL astro guy sent out the announcement that the Chinese
Space Station Pass is Tuesday -- aka TONIGHT, Heavens Above - our source
says it is Wednesday Nov 2. Look tonight to verify? And have a nice
look at a very thin crescent moon and Venus/Saturn. And try again
tomorrow night, which is what we think is the correct date.

What's Up Sept 2016:
African Eclipse, metoers, planet pairs
https://youtu.be/n_2rgiyJ5Pg
Hi everyone, my What's Up November video is out, and there is a pretty
lineup of moon and planets the next 3 nights, so I thought I'd send out
an additional reminder to step out and look up!
From November 1^st to 3^rd , catch gibbous Venus (phase visible in
telescopes, may look "oval" in binos, the crescent moon, and ringed
Saturn together in the southwest sky just after sunset.The prettiest
triangle of the three is Thursday night, so go out and practice just
after sunset.
Then also tonight, there'sa very good pass of the Chinese Space Station
just after 7:00 PM for SoCal. This is probably the last real
opportunity to see Tiangong 2 while the Chinese astronauts are still
onboard. Jing Haipeng and Chen Dong are half way through
their month-long flight. The station reaches 10 degrees above WSW
horizon 7:06:53 p.m. (Very near the moon/Venus/Saturn trio) Maximum
altitude 67 degrees NNW at 7:09:57 at magnitude 1.2, brighter than the
most of the stars it passes until it disappears into Earth's shadow near
fainter Cassiopeia stars. Let me know if you see it!!
There are also some famous meteor showers -- famous from past outbursts,
but rates will be lower due to bright moons nearby, but still any chance
to see a Taurid on the 12th, a Leonid on the 17th or an Orionid on the
28th, is worth it if you are awake and the sky is clear on or near the
peak nights!
Mojave National Preserve Star Party is this weekend! RSVP here on the
Facebook Event - or ask me for phone/email to RSVP
https://www.facebook.com/events/310376066006443/
Eclipse info - no new news, but some of your fellow members of this
email list have reserved two of the camper sites next to us in St.
Anthony ID, and there are plenty more sites available. Info was on the
last email. And the Idaho Museum in Idaho Falls will have some cool
exhibits (and speakers :-) the day before the eclipse) It's gonna be epic!!

ISS Pass (from LA area): Time: Fri Oct 21 6:31 PM, Visible: 6 min, Max
Height: 58°, Appears: 10° above NW, Disappears: 12° above SSE- Get your
own alerts for your location here --> https://spotthestation.nasa.gov/
The August 21 2017 total Solar Eclipse is only ten months away! It will
be visible in the US from Oregon to South Carolina -- in a thin path
only about 60 miles wide.
https://solarsystem.nasa.gov/planets/sun/2017eclipse
If you are wondering where to go to see it, scroll down to "Find Your
Spot" on the toolkit link above -- and click on the Google Interactive
Map to see the eclipse path, anywhere you click, you'll get the time and
totality length. In the west, totality can be seen only in a narrow
path through Oregon, Idaho and Wyoming. The maximum totality (minutes
and seconds) reaches 2 minutes 40 seconds near St. Louis, less in the
west and east of maximum. Here are some examples of totality length near
the centerline in the western states:
1 minute 55 seconds in Salem -- Bend, Corvallis and Portland all will
have a partial eclipse.
In Wyoming, Casper has 2 minutes 25 seconds,
In Idaho, Rexburg gets 2 minutes 17 seconds of totality, while Idaho
Falls, 29 miles south gets only 1 minute 41 seconds.
Many hotels along the centerline are completely booked already. We
wanted to drive with our telescopes for dark sky observing at night, and
so we'd have flexibility to dodge clouds on the day or day before the
eclipse, and rented a trailer. We found an RV park just 12 miles north
of Rexburg ID, very close to the centerline. Our location will see 2
minutes 3 seconds of totality.
This RV park still had lots of spaces available (and restroom/showers
and a store) http://www.idahodunesrv.com/ <UrlBlockedError.aspx>
The rates for "Special Events" like 4th of July, Labor Day and eclipses
increase double (to $70 per night) for our large space
https://www.idahodunesrv.com/reservations.php
On this map is the campground layout
https://www.idahodunesrv.com/map.php <UrlBlockedError.aspx>
We rented the end space in the end row, space 56 on the map above for 4
nights August 19-22. We plan to join the Idaho Falls Astronomy Club at
one or more of their dark sky star parties in the evenings before the
eclipse, or possibly even set up in the RV space and share views with
other campers, if the lights aren't too bad.
There will also be livestreamed events of the eclipse for the armchair
sun worshipers, more on that as time nears. And here's what the partial
solar eclipse will look like here in the LA area.

A really nice ISS pass everyone!!

Later..... at 10:25 p.m. a lunar grazing occultation!
*Who:* Magnificent red Aldebaran, the "eye" of Taurus the bull appears
to approach the moon's sunlit side, close to the north pole. Soon the
star will be easy to see as it moves onto the dark side of the moon. If
Aldebaran was placed where the sun is now, its surface would extend
almost to the orbit of Mercury. It's also about 153 times brighter than
the sun.
Good image here:
http://occultations.org/wp/wp-content/uploads/2016/06/MoonViewWithCaption.j…
*What:* A lunar occultation occurs when the Moon, moving along its
orbital path, passes in front of a star or other celestial object, as
seen by an observer (normally on the Earth). A grazing lunar occultation
occurs when one of the two edges of the moon parallel to its orbital
path appears to just touch or graze the object as the moon goes by. When
this happens, a properly positioned observer will see the grazed object
disappear and reappear, possibly several times, as mountains and valleys
on the edge of the moon pass in front of it.
*Where:* Along a very thin line from Los Angeles, through Denver, Sioux
Falls, Minneapolis!
http://occultations.org/wp/wp-content/uploads/2016/06/20161019_AldebaranGra…
*When:* Greater Los Angeles area 10:25 - 10:29 p.m.
