ISS Pass again tonight. Time: Sat Feb 09 6:53 PM, Visible: 5 min, Max Height: 48°, Appears: 10° above
WNW, Disappears: 26° above SSE
The forecast is partly cloudy, Gary just stepped out and sees increasing clouds and no visible moon. The temperatures are dropping, and none of the astronomers appear to be available tonight, so we won't be bringing telescopes out tonight for all those reasons. If you feel so inclined, and can see some patches of sky, step outside to see the ISS pass at 6:52 p.m. and look for the slim crescent moon. It's 22% illuminated, and sets at 10 p.m. We may try again next Saturday but some of us are not available then either. Hang in there for better weather and less busy volunteer astronomers.

may cancel Saturday Sidewalk Astronomy. Here's the forecast. I'll post a
go/no-go on the website, and maybe a quick email on Saturdayo.

Most of the Sidewalk astronomers are staying home, otherwise engaged, or
doing school or scouting events that aren't reliant on guaranteed
viewing tonight. We have been looking on Weather.com, or weather
underground and the forecast is cloud cover/poor transparent skies for
Pasadena and much of Southern California. Your eyes are the best
observing tool for lunar eclipses. So take a break from the football
games and check out the sky after 7:30p.m. that's when the first "bite"
will show. I like to sketch the moon, and one thing you could do is
draw some circles like the sketching example (on a sheet of paper
secured on a clipboard.) Fill in the amount of shadow you observe and
show the time you observe it below your sketch and draw or mark any
prominent features you see. I'll try to do the same at my scouting
event tonight.
Sketching example from Erika Rix publisshed in Astronomy Magazine:
http://www.astronomy.com/magazine/erika-rix/2014/08/sketching-a-lunar-eclip…
Lunar features annotated
https://en.wikipedia.org/wiki/List_of_lunar_features#/media/File:Moon_names…
Here are times of key eclipse events:
before eclipse - note the features you see on the full moon
7:33 pm Moon enters the Earth’s inner shadow (first bite)
8:40 pm Totality begins (moon is covered in shadow)
9:12 pm Mid-eclipse
9:43 pm Totality ends (moon emerges from shadow)
10:51 pm Moon exits the earth's inner shadow
One or two astronomers may be on the corner of Myrtle and Lime from 7:30
- 8:30 or 9 tonight, to look for the moon through the expected clouds
and possibly aim binoculars if there are fleeting views. Don't make a
special trip, but if you are planning to walk around Monrovia tonight,
you may see an astronomer or two with binoculars, no promise of a
telescope. I don't think the astronomers will stay past the beginning
of totality at 8:40 p.m., so your best bet is to look up from your own
place if you can see the moon. Your eyes turn out to be the best
instrument for viewing lunar eclipses. I'm bringing binoculars and
wishful thinking to a girl scout event tonight.
From the Griffith Observatory announcement:
NOTE: The eclipse will be visible to the naked eye from anywhere in
southern California if skies are clear. You do not need a telescope.
It is safe to view a lunar eclipse without any eye protection.
Griffith Observatory has a warning about crowds, and traffic and lots of
great info here. If you plan on going, be prepared to either go several
hours before 7:30 p.m. or go late, and park miles away & walk.

There are other cool astronomical events coming up so don't let the
clouds dampen your stargazing enthusiasm!

NASA's January What's Up has not been posted due to partial gov't shutdown, sorry, but I'm retired!
We've been carefully watching the forecast for a couple days before
posting a go or no-go sidewalk astronomy decision for tonight, January
12th. But I think Gary's morning forecast note "Now says rain all day
until 6pm instead of being done around lunch, I think that seals the
fate of this evening." sums it up. Once again weather wins over sidewalk
astronomy, and we are cancelling sidewalk astronomy tonight.
But next Sunday there is a total lunar eclipse you'll be able to see
from home, any cloud free part of the Americas. For those easily
confused between UTC (Universal Time) and your local time, the eclipse
begins at 9: 12 PST and the totality portion is between 8:41 p.m. and
9:43 p.m. More details here, and you can change the location if you
aren't local to us here in LA.
https://www.timeanddate.com/eclipse/in/usa/los-angeles?iso=20190121
As the week progresses and we return from a month of travel, we'll post
some viewing spots.
That's all from Jacksonville FL, gotta board my flight home now! Jane

Sidewalk Astronomy Myrtle and Lime Monrovia Saturday, sunset for 2+
hours, weather permitting. It looks like clear skies for Saturday night.
Look up, if you can see the moon, then walk on down! There will be at
least three telescopes out and Mojo and I are out of town.
Geminids peak today (actually best from dark sky both Friday and
Saturday mornings) so good luck! Here's a great page written by our
friend from the 1999-2002 Leonid Storm observing campaign, Bob
Lundsford:
https://www.imo.net/viewing-the-geminid-meteor-shower-in-2018/ You will
see how the rates have picked up from the 12th to the 14th, and rtes
will still be nice and bright tomorrow morning, and then will start to
decrease. https://www.imo.net/members/imo_live_shower?shower=GEM&year=2018
Lunar Eclipse Jan 20 -- from about 6:36 p.m. to 11:48 pm Pacific Time
with total eclipse at 9:12 p.m. There will probably be some astronomers
on hand at Library Park -- I'll let you know next month. But lunar
eclipses are great to view with the unaided eye, so you can enjoy them
at home, too.
Jan 21, 2019 at 02:36:29 UTC is the time in UTC so you can calculate the
time in your own time zone. Or use this handy drop down menu:
https://www.timeanddate.com/eclipse/in/usa/los-angeles?iso=20190121
Finally some of you have asked if just because we are retiring from our
day jobs (me this month, Mojo in March) will we also be retiring from
sidewalk astronomy or moving way. The answers are no and no. We love
our Old Town Sidewalk Astronomy family, our growing telescope yielding
group and our many astro-fans who join us for viewing events, or read my
emails.
Happy star-trails everybody! The last "What's Up" video from me is here
https://go.nasa.gov/2DUnUsg, but the show will go on with a new voice in
January. The amazing Henry Kline will continue to produce the show from
the JPL TV studio, so I'll keep sharing it with you!

What's Up #137: Nov 2018 Planets, asteroid, comet, Leonids
https://go.nasa.gov/2zlrCaF
All 137 What’s Ups since 2007: https://go.nasa.gov/2usaBaB
Hi everyone! The forecast is not very promising for tonight, with both
poor transparency and possible clouds, so we are cancelling sidewalk
astronomy. Looking at last night and the fog this morning, it looks
like a repeat of the same (according to astronomer Gary).
Our next scheduled sidewalk nights are December 15th and Jan 12th. We'll
also have an added event January 20th -- A Sunday night, when a total
solar eclipse will be visible for much of the US. The eclipse begins at
6:36 p.m., reaches maximum at 9:12 p.m., and ends at 11:48 p.m. We'll be
on the sidewalk in Monrovia at least until maximum, then you can finish
watching from your own place. Here are the details.
https://www.timeanddate.com/eclipse/in/usa/los-angeles?iso=20190121
Tonight/tomorrow morning is the peak of the Leonid Meteor Shower, if it
is clear where you are before dawn tomorrow and you are in a dark spot,
you might see some, tho the rates will be poor. Next month, the
Geminids will put on an impressive show on December 13th and 14th.
December’s Gemind meteors peak on the morning of the 14^th at 12h 30m
Universal Time, (or 7:30 a.m. Eastern Standard time, 4:30 am Pacific
Standard time) and are active from December 4th through the 17th.The
peak lasts for a full 24 hours, meaning meteor watchers around the globe
will get to see this spectacle. If you can see the familiar winter
constellations Orion and Gemini in the sky you'll see some Geminids. 120
meteors per hour may be seen from a very dark sky location during the
peak, but only after the first quarter Moon sets around midnight your
local time. Definitely check it out if you can!
That last paragraph is a "preview" of "What's Up" for December, which
will go live December 1st (or probably the 30th of November). That will
be my last project before I retire from JPL on December 3rd! I'm
definitely not retiring from the Old Town Sidewalk Astronomers or from
sending out these emails to you. I look forward to many more star-filled
nights, and sunny solar viewing days sharing our skies with you! Jane
