This past weekend was "new moon" when we often take the opportunity to
get out from under the Los Angeles light dome and see the real night
sky. This weekend's was a fun observing trip for planets, lightning,
meteors, and a great night sky. I have pictures and an observing report
here:
http://mojo.whiteoaks.com/2010/08/09/sky-full-of-planets-and-lightning/
Next new moon weekend coincides with the Labor Day weekend, Sept. 3-6,
and we'll be joining the San Jose Astronomical Society in Yosemite
National Park at Glacier Point for three nights of great observing in
one of the best night skies on the planet.
We'll have sidewalk astronomy in Monrovia next weekend, and Pamela Park
the following weekend. More on that in a few days.
Jane will post some more about the Perseid meteor shower later this
week, and right now you can enjoy her What's Up podcast about the
Perseids here:
http://www.youtube.com/watch?v=GxBc4dA37So
The meteor shower is ongoing with a peak Thursday night / Friday
morning, but good meteors all week.

The Perseids will make summertime extra special this year because the moon
will not interfere with the meteor show. Plus, as a bonus, a trio of planets
plus the moon make a sunset appearance on the nights surrounding the peak of
the Perseids on August 12-13. Our solar system is on display 24-7!
This month's What's Up podcast features the Perseids, naturally! It has
some nice animation of the why and where of meteors, and talks about all the
upcoming comet and asteroid missions. It also touches on Mars in August, and
offers a good night to use that Mars hoax email to practice some critical
thinking skills. On August 12-14, the moon and Mars appear near one another
for all to see and compare.
On the Solar System Exploration website are all the many formats of the
video. Including some with captions - perfect to show on a screen in a busy
planetarium or museum without audio. I included some edible rocks and
asteroid recipes this month in the education section. I've also linked to
"the Fluxtimator" to see how many meteors you can see in your area.

For the past eight years, I've updated a Mars in August page, and this year
I use it as a great way to teach critical thinking to the public. If you're

Next month (September 2010) my video will be about the moon for
International Observe the Moon night. http://observethemoonnight.org/

On the way home from the movies, Jane snapped a lovely picture of the
full moon rising over Pasadena.
I realized that there was a fun short beautiful astronomy lesson to be
had in that one post. Did you see this lovely moon tonight as well?

Old Town Sidewalk Astronomers http://otastro.org
I was asked by a colleague to see if anyone might want a free telescope,
complete with eyepieces. I asked him to take some pictures, and I am
offering it to our Sidewalk Astronomy email list first. When I saw the
pictures of the telescope, I just had to tell a story about it, so
here's the story and the free telescope offer. First person to call
Steve and arrange pickup will get it. Don't call or email me with
questions - I am out of the office and traveling until Monday.
http://jane.whiteoaks.com/2010/07/20/free-telescope-to-first-caller/
Steve is also featured in this awesome video from Cassini today. It's
comparing Titan's lakes to Death Valley's Racetrack Playa and the video
is on this page.

Finally, back to the solar system. :-) I was in Washington DC last
week as part of NASA's 400 years of Discovery - from Galileo to the
Outer Planets exhibit in the U.S. House of Representatives Rayburn
Office Building. The day of our event was also the 400th anniversary of
Galileo's first telescopic look at Saturn. so I wrote this little piece
about it for our NASA Solar system Exploration website. Ta da!

Here is what the exhibit looked like:

What's Up for July? Dark Nebulae http://sse.jpl.nasa.gov/news/index.cfm
Summer has definitely arrived in L.A., and it's promising to be a hot
weekend! It's also the weekend of the first-quarter moon, when you see
a roughly half-moon in the early evening sky. You might have noticed it
growing from a small crescent this week as it passed by Venus, Mars, and
Saturn after sunset on successive nights.
This weekend we'll be serving up views of the moon, Saturn, and Venus to
accidental astronomers at Pamela Park in Duarte, and Old Town Monrovia.
Tonight instead of Old Town Pasadena, the astronomers will be set up in
small Pamela Park in Duarte. L.A. is keeping several county parks open
past sunset this summer. Look for telescopes there tonight between 8:00
and 10:00 p.m. The park's official web page has its location just south
of Duarte Blvd.:
http://parks.lacounty.gov/Parkinfo.asp?URL=cms1_033233.asp&Title=Pamela%20P…
Saturday we'll be at our usual spot in Monrovia at the corner of Myrtle
and Lime at Library Park from 8:00 'til 10:00.
Now here's a kick -- Monrovia is putting on free outdoor movies in
Library Park this summer, and Saturday evening they'll be showing _Star
Wars_. Last month this turned out to be a great combination activity,
and we had one of our biggest turnouts in Monrovia. Between the hot
summer day and the movie in the park, we should have good crowds this
Saturday as well.
Finally, if any of you still have a telescope in the closet that you've
never quite figured out how to set up, I'll be happy to meet you in
Monrovia at our Library Park location at 7:00 with my box of tools.
Drop me a note if you'd like to do this. If I don't hear from you I
won't be there.

Old Town Astronomers: http://www.otastro.org
I've just updated the otastro.org website with July and August dates for
our sidewalk astronomy events. On July16, a few of us will be at Pamela
Park in Duarte for a new venue tryout from 8-10 p.m. July 17th is our
Monrovia sidewalk date, same hours again - from 8-10 p.m., and just like
last month, it will coincide with Monrovia's free movie in Library Park.
Both movies and stargazing start "8-ish", but we'll target the moon
before it gets dark at 8 p.m. Wow, see stars AND Star Wars! What could
be more perfect?
Tomorrow night, that's Saturday, July 3rd, a few of us are heading out
to the hot desert for a night of stargazing. The moon will rise at about
1:30 p.m. but it will be the third quarter moon, a beautiful lunar phase
too few stay up late enough to see. It will be hot. At Desert Center,
CA (the closest town) temperatures are predicted to range from a high of
102 to a low of 75. We'd welcome people to join us on our little piece
of astro-heaven - 2 miles of washboard dirt road off the I-10 freeway.
Wear sturdy rattlesnake and cactus needle-proof hiking boots, and dress
for warm weather, but bring a jacket. There are no facilities on this
unimproved stretch of BLM land I do bring a PET (portable environmental
toilet). And bring plenty of water. We'll leave at 3 p.m. from Monrovia
so email before then if you need details or a map.We will arrive by 7
p.m. There is room for half a dozen cars in very soft sandy ground
(trucks and RV's have sunk into the sand).
But seriously, most people will be staying home readying for Fourth of
July festivities, so I have prepared a home-observing project for you
all, and it doesn't even require a telescope. Why not try to see
Galileo's famous third quarter lunar view Saturday or Sunday morning
after midnight and before dawn? Galileo made a series of lunar sketches
in 1609, and on December 18, 1609 (4:00UT), he sketched this view of the
lunar surface.
http://jane.whiteoaks.com/2009/08/31/chasing-galileo-22-day-old-moon-compar…
This is the same view you will have over the next two mornings. :-)
So step outside this weekend and aim your binoculars at the moon, and
get a sense of Galileo saw 400 years ago. If you are interested in
observing all of Galileo's views, here is a table of modern dates to
complete the project. I did it and it was a great learning and observing
project. http://www.pacifier.com/~tpope/Reproducing_Observations.htm
You can see the third quarter moon in the daytime, too, tho' the
contrast isn't as great in the bright sun. The moon rises at about
midnight tonight and sets at about noon, then a smaller crescent rises
later each morning until new moon phase in the 10th.
Have a safe and sparkly weekend, everyone! Jane

For those of you escaping the urban jungle this holiday weekend, pack a pair
of binoculars and enjoy the glorious Milky Way after the sight of fireworks is over.
A pretty march of the planets is underway too. Mars and Saturn are inching
closer to one another (from out vantage point on Earth, that is) with Venus
not too far away - all grouped in the western sky at sunset.
The sky looked exactly like the images in this month's What's Up podcast at our
recent desert outing. In fact, nearly all the astrophotos in July's podcast were
taken on that June 12-13 night by Mojo from our dark sky astronomy location.
Out next outing should be July 10. If you are interested in seeing an
amazing summer sky through big and small telescopes, let me know. We haven't
quite decided if and where we'll go, as the desert heats up in the summer, even at night!
I have a new webpage for my What's Up podcast and occasional blog entries on our
NASA Solar System Exploration website.
Here's the new News and Events webpage, and from
here you can get to this month's podcast and more.
http://solarsystem.nasa.gov/news/index.cfm
And join me and take a stroll through the new Solar System web content.
My group at work has been developing, writing and coding it for a year now!
There is great kids content! I double dog dare you to try these puzzles!
http://solarsystem.nasa.gov/kids/puzzles.cfm
YouTube version of the podcast is easier for some people so here is the link: http://www.youtube.com/profile?user=JPLnews#g/u
We'll keep you in the loop with regard to celestial happenings, and we both have some work travel this month. I get to go to Washington DC and be Galileo with my Galilean telescope replica. :-)

Hi all!
Because of other commitments, we're not going to be able to set up in
Pasadena tonight, but the weather looks good for tomorrow Saturday
evening in Monrovia. We'll be at the corner of Myrtle & Lime from about
8:00 'til 10:00 p.m.
We should have good views on tap of the moon and Saturn, with possibly
some looks at Venus.
If there are still some folks who want help setting up a new telescope,
drop me a note. I'll be happy to meet you on the corner at about 6:30
while it's still daylight.
On "new moon" weekends like last week, we frequently travel out to the
Colorado Desert south of Joshua Tree. Jane and I both wrote some great
reports on last week's observing. Jane had a "Ten Planet" observing
night, while I captured some fun astrophotos:

If you were to pick a weekend for all-night stargazing, this weekend
would an excellent choice! From dusk on Saturday all the way to dawn on
Sunday you'll be treated to a starry necklace of planets, all strung out
along the ecliptic plane of our solar system. By midnight or so the
Milky Way will begin to span the sky, too! It will be possible to see
all 8 planets, 10 if you count Ceres and Pluto (from a dark sky, that
is). ;-)
Planetary jewelry is topic of the June what's Up podcast, by the way,
which you can download from the Solar System Exploration website,
complete with additional links.
http://solarsystem.nasa.gov/news/whatsup-archive.cfm
Also on the JPL website: http://www.jpl.nasa.gov/
and YouTube: http://www.youtube.com/profile?user=JPLnews#g/u
In addition to the great planet lineup, early risers will also see a
comet, and an asteroid or minor planet, plus you can hunt for Pluto, now
demoted to dwarf planet status, but still very special. To see the comet
- Comet C/2009 R1 (McNaught) scan the NE sky with your binoculars 15 -20
degrees above the horizon - it will be near the brightest star of
Perseus, Alpha Persei or Mirfak - ahhh, that was where the pretty Comet
Holmes was just two years ago! It is on the edge of naked eye
visibility, which is made difficult due to the low horizon + the
nearness of dawn.
Comet McNaught gets 1 degree lower every night after the 15th, until it
is lost from our view as it reaches perihelion, or its closest approach
to the sun on July 2nd. This weekend is the best and nearly the last
time to see it. If you snooze through this one you will definitely lose!
Minor planets? Dwarf planets? You betcha! Ceres and Pluto are to be
found right smack in the thickest part of the summer Milky Way - in the
"steam" rising from teapot-shaped Sagittarius constellation. Pluto
skims the star cluster M24 and Ceres just stepped out of the Lagoon
Nebula, M8. Both the "M's" are naked eye clumps in the Milky Way, and
glorious in binoculars. Early morning just before looking for comet
McNaught will be a fine time to hunt these two down from a dark sky with
a good skychart or star tour guide.
From the greater LA area you can still see the brighter planets and you
can try for the comet. It doesn't rise until 2 am and the best time to
see it will be when it is as high as it gets, just before the the crack
of dawn. You need a pretty decent flat horizon (aka no mountains, hills,
trees, buildings) to your Northeast. It will only be about 20 degrees
above the horizon at its highest. You may see the comet, and some of the
faint tail. You won't see the detail shown in astrophotos - those are
time exposures, and our eyes don't have those settings, unfortunately. :-(
Almost every month your Old Town Sidewalk Astronomers step away from the
sidewalk, drive 150+ miles each way, take big and small telescopes out
to some of Southern California's great dark sky locations. We are happy
to take friends on star tours - but ask first as some of our locations
only have room for a couple extra cars (also no trucks or RV's this
weekend for example) You can enjoy the darker skies all summer long from
many city, state and national parks with nothing more than a pair of
binoculars! Pencil in these dates to check against your calendars -
these are the dark sky weekends. The week before these is also decent.
June 12, July 10, August 7th and September 4+11. September 4th some of
us will be at Glacier Point in Yosemite serving up free public
stargazing. Anyone in the park is welcome to attend and look through the
San Jose Astronomical Association's member telescopes, if you are hiking
in the day, bring layers for the night. Glacier Point has astronomy
every weekend from July 4 - Labor Day, with different astronomy clubs
from Northern California sponsoring each weekend, except for the full
moon. Members bring telescopes, guests get looks all night long, weather
and telescope operator endurance permitting, that is.
That's all for this month, :-)
