A really nice ISS pass everyone!!
Time: Tue Oct 18 7:32 PM, Visible: 4 min, Max Height: 79°, Appears: 10°
above NW, Disappears: 45° above SE
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:

*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!

*When:* Greater Los Angeles area 10:25 - 10:29 p.m.

Saturday is International Observe the Moon night, and also Astronomy Day
or both. For us, it's just our regular Saturday night closest to the
first quarter moon -- the Saturday each month we bring the moon and
planets (weather permitting) to the sidewalk. There are some other
events Saturday the 8th in the bandshell on the other side of Monrovia
Park, so come on down and enjoy the various afternoon and evening events
by walking around the park! The big Library Park would make a great
scale model of the solar system, with the sun at the fountain, wouldn't
it? So come out and join us!
When Oct 8 6:30 p.m. - 9:00 p.m. Myrtle/Lime corner Monrovia CA
Other events coming up:

Hi everyone, and welcome to a few new members of our email list!!
Tonight is a great chance to see the International Space Station (ISS)
pass over southern California. You'll want to step outside and
familiarize your self with where your SW horizon is. the station looks a
bit like a moving n on-blinking airplane. It will be visible about 10
degrees above the horizon (90 degrees is straight overhead) at 8:02
p.m. by 8:05 it will be neasrly overhead -- 78 degrees high moving from
SW to SE. BY 8:06 p.m. it will be dipping to 61 degrees above the ENE
horizon and it will disappear as it enters the shadow of earth.
There are a couple more, on the 28th two passes beginning at 7:10 p.m.
and again 8:49 p.m. - but they do not rise above about 30 degrees above
the horizon. One on the 29th 7:54 p.m. and another very good one on the
30that 7:02 p.m. reaching 78 degrees above the horizon SW --> NE and
another one that same night at 8:41 p.m. only reaching 11 degrees above
the horizon - those two days with two passes? That is how long it takes
the ISAS to orbit Earth -- a little over an hour and a half!

Next astro events: Monrovia October 8, sunset - till 9 p.m.-ish.
October 8th is Astronomy day all over the world and also International
Observe the Moon night -- I talk about THAT in the October What's Up,
which will be published Sept 29th because month-end is all about the
Rosetta Mission end of mission. Google that for more info.
For dark sky events, our next Mojave National Preserve star party - Free
entrance to the park, free campsite, a potluck and free looks through
our telescopes November 5th.
And this weekend a few of us are going to Amboy Crater for sort of
personal observing. If you are interested in joining us and looking
through my telescope, I'll send directions, travel time (3 hours from
Monrovia, not really a campsite, we sleep in our cars) But you could see
some dark skies or bring your own equipment -- important to arrive well
before dark, as there are no lights on Route 66 to see the turnoff.
See you all under the stars, or planets or streetlights!

What's Up Sept? African Eclipse, Minor Meteors, Moon Neptune

The Perseid rates started to riselast week! This chart will be a fun
way to see what worldwide observers are seeing in real time hour by
hour. http://www.imo.net/live/perseids2016/. The best location is one
devoid of any nearby light pollution, so if you are observing at home
find the spot against a shielding wall without direct streetlights,
motion sensor lights, etc. Mojo and I will be in Lockwood Valley
Thursday night till dawn Friday morning, and at our annual "Stars Over
Yosemite" star parties Friday and Saturday nights. Free with entrance
to the park,every weekend excepting full moon thru Labor Day, a
different astronomy club's members hosts the weekend events.
Here are some tips and times. I cut out the pertinent few sentences, but
the writeup is very good and written by a personal friend, Bob Lundsford
who Mojo and I have worked with on NASA Meteor Counting Campaigns since
1998! Excellent graphics, too!
http://www.amsmeteors.org/2016/08/viewing-the-2016-perseids/
* "Every year, the dust particles from the tail of the Swift-Tuttle
comet pass the Earth orbit and burn in our atmosphere (about 70
miles / 110km above us) from mid-July to the end of August. When the
dust and ice hits our atmosphere at around 37 miles / second
(59km/s) they disintegrate high up in the atmosphere after making a
brilliant flash of light. Most of these particles are the size of
sand grains, while a few are as big as peas.
* *Maximum activity is predicted to occur on the morning of August
12^th *, when rates in excess of *1 per minute* may be seen from
dark sky sites. On the morning of maximum the waxing gibbous moon
will set between midnight and 0100 local daylight time as seen from
mid-northern latitudes. This will free up the prime observing hours
from interfering moonlight.
* As the night progresses the Perseid activity will slowly rise as the
radiant gains altitude in the northeastern sky. Not until after
midnight will the Perseid radiant gain sufficient altitude to
produce pleasing results. Anytime from moonset to dawn will be the
best time to see the most activity. Perseid meteors will appear in
every portion of the sky. I would suggest facing toward the
direction with the flattest horizon, devoid of any trees or hills
that may block you view of the meteors. If all directions are
favorable, then face toward the darkest portion of the sky, opposite
any terrestrial lights that may interfere with viewing.
* The best Perseid rates will occur on a 5 night segment centered on
August 12^th . So if August 12^th is cloudy you can still see good
Perseid activity over the weekend. Just be sure to wait until the
moon is low or has set before attempting to observe.
* *The best night for viewing the Perseids will the morning of August
12^th .* This year predictions by Mikhail Maslov and Esko Lyytinen
predict that we will cross a part of the stream which has shifted
closer to the Earth’s orbit by Jupiter. Therefore rates could be up
to twice as high compared to a normal Perseid display. Normal rates
for this shower are usually around 60 meteors per hour as seen from
rural observing sites. *Therefore this year rates could exceed 100
per hour.* Note that meteor activity is notoriously bunched, meaning
that there are periods in which you will see no activity and other
times when you will see several within seconds of each other. The
quoted rates are an average over an hour’s time.

A few of us will be out on the corner of Myrtle and Lime tomorrow night
Saturday July 16. We'll have nice views of the moon, Saturn and Mars,
and early birds may see Jupiter, either with the unaided eye (probably)
or telescope ( trees/buildings).
Upcoming dark sky events:
August 12/13. Yosemite Glacier Point. Telescopes via selected club
members only ( we are with the San Jose Astronomical Assn) this weekend)
but all park guests welcome at the Glacier Point ampitheatre. If you are
at Yosemite this summer, check the schedule ( no full moon weekend) Just
come up, park an
Mojave Star Party November 5th - Many list members attended June event.
One comment: "So many kids for my daughter to play with" Another - kid
with telescope wowed everyone.
We do travel to dark sky areas - typically 90 - 200 miles one way most
new moon weekends. If you want to join us, send me a note for more info
on our dark sky events. Plan to sleep in car or drive 3 hours there/ 3
hours home. I will make a small list of who ever wants to join us for
super dark skies, bring your own telescope or use ours. Many local asto
clubs with less trvel. You can find.
Finally, this month's What's Up features many astrophotos from Mojo -
all taken at our favorite Amboy Crater dark sky locations. It's 180
miles from Monrovia, no camping (car camping ok, terrain is LAVA, so no
place to pitch a tent.

Several of us are out of town or on vacation, or welcoming a new baby
but Mojo and I want to get out with telescopes and show Jupiter, Mars
and Saturn, plus the moon tonight. Sunset is at about 8 p.m. so wander
by our Sidewalk Astronomy corner -- Myrtle and Lime streets in Monrovia
between 8 and 9:30 p.m. It should cool to about 79 or 80 degrees by
sunset. :-)

Well, no chance of sidewalk astronomy in Monrovia tonight. Bu behind
those clouds are some gorgeous views of the planets Saturn, Mrs and Jupiter.
Learn what's up this month in my monthly podcast
https://youtu.be/M7RtIa9zBYA, transcript here (and feel free to share!)

Tonight's weather isn't this "reverse clearing" but still, this is a
very interesting chance in our May Grey/June Gloom weather - clearing at
the coast, high fog lingering up against the mountains.
http://www.scpr.org/news/2016/05/18/60754/la-s-may-grey-unusual-this-year-t…
And just as a reminder, our free dark sky star party in the Mojave
National Preserve is June 25th - just two weeks away. Weather
permitting, the Milky Way will be glorious!
A few links and info I have sent our to several of you who plan to attend:
Our star party is held at the Black Canyon Group Campground (close to
the Hole-In-The-Wall visitor center and campground) in the middle of
Mojave National Preserve. about 170 miles from Monrovia.
A*RSVP* is required, but there is no charge for the event -- the RSVP is
for # of tents/cars. There is a facebook group and you can RSVP there
https://www.facebook.com/events/695749230564590/, or you can call or
email our wonderful coordinator from the Mojave National Preserve
Conservancy David Lanfrom dlanfrom(a)ncpa.org or 760-219-4916 - he is
the best person to answer more questions.
The directions are here -- the last quarter mile is not paved:
https://www.nps.gov/moja/planyourvisit/directions.htm
Directions to Hole-in-the-Wall
From I-40:/ Exit Essex Road and drive north 10 miles to the junction
with Black Canyon Road. Hole-in-the-Wall is 10 miles north on Black
Canyon Road.
And here is a zoomed in version of the area centered on the Black Canyon
Campground --
https://www.google.com/maps/@35.04204,-115.3879753,2413m/data=!3m1!1e3
It is a very large group campsite, with plenty of parking.
Arrive before sunset (which is at 8:08 p.m.), and there will be a
potluck beginning at about 6 p.m., with rangers from the National Park
Service, members of the Mojave National Preserve Conservancy and the
sidewalk astronomers and all our guests all sharing the potluck, and a
few saying a few words to the group. There is a large firepit, covered
pavilion with 8 picnic tables, trash/recycling critter-proof cans, a
pump with water for washing dishes, and pit toilets, which you can see
if you zoom in close on the google map. You can also see the circular
parking area and the large sandy/brushy area for tents. So bring a tent,
sleeping bag (or car camp), pot luck or bring something to eat for
dinner, there is room for camp stoves on the picnic tables if you want
to cook. The Conservancy provides lots of drinks, chips, some food,
there is always vegetarian food, but you can bring your own. A local
family often makes tamales (both meat and vegetarian), and/or soup or
stew, again veg/meat.
All the guests come up and spend time at the telescope, white
flashlights are not appreciated at the telescopes, we suggest not using
the flashlight at all at telescopes. As your eyes adapt you can see very
nicely without lights. But our star party is very informal, and we just
ask people to cover flashlights with your hand, and turn them off at the
telescopes, no cell phones or iPads or other light emitting devices up
at the telescopes preferred. Most people spend time at the tables eating
or snacking, or talking and storytelling at the big fire pit, Dogs are
permitted and there are usually several -- some on leashes and some not,
all very nice dogs. Kids are welcome.
