Sidewalk Astronomy tonight 8p.m. Monrovia

by Jane Houston Jones

Ladies and gentleman, boys and girls, in just a few short hours we'll be setting up a few telescopes at Myrtle and Lime Streets in Monrovia to share views of Saturn and the moon. Can you tell I just returned from a Disney Cruise to Alaska? :-) (photos linked to my signature line, if you want to be tortured by our photos) Sunset isn't until 8:00p.m. so we will show the moon until about 8:30, then moon and Saturn until about 9:30 p.m. If you miss us, you can still see the moon and Saturn from your back yard. To see what else is up this month here's my monthly video: http://solarsystem.nasa.gov/news/whatsup-archive.cfm And read more about what's up all year on my blog: http://jane.whiteoaks.com/2013/01/07/whats-up-in-2013-at-a-glance/ -- Jane Houston Jones Monrovia, CA What's Up Podcast for June: planet lineups & telescopic asteroids http://solarsystem.nasa.gov/news/whatsup-archive.cfm Alaska vacation pictures http://photo.whiteoaks.com/2013-06-alaska/ 2013 Astro Calendar: http://jane.whiteoaks.com/2013/01/07/whats-up-in-2013-at-a-glance/

Sidewalk astronomy tonight!

by Jane Houston Jones

There may be thin clouds overhead, but a few of us will be out at Myrtle and Lime Streets in Monrovia with telescopes tonight anyway. On tap will be the moon for sure, Jupiter setting early and Saturn rising. Last weekend 11 of our intrepid Sidewalk Astronomer family headed out to Black Canyon Group Campground in Mojave National Preserve for the spring version of our twice-a-year public dark sky star parties. A fabulous time was had by all - there were about 70 people there and 7 telescopes to look through. Here is a writeup from one of the many media there: http://www.lacanadaonline.com/news/tn-vsl-0515-a-star-party-in-the-desert,0… And here is my monthly video, all about spring constellations, and how you can find them when they are close to the moon (like Leo and the moon tonight!) Each of the constellations I cover this month yields beautiful deep sky objects we love to observe in the dark skies of the desert, with astrophotos contributed by Mojo. http://youtu.be/sqnHaIYn_tc Our Otastro website has May viewing tips and the next star party dates http://www.otastro.org/ Jane and the astro gang -- Jane Houston Jones Monrovia, CA What's Up Podcast for May: Spring constellations On Youtube: http://youtu.be/sqnHaIYn_tc Twitter: http://twitter.com/jhjones /CassiniSaturn /otastro My Blog: http://jane.whiteoaks.com/ Yosemite Star Party Video http://www.youtube.com/user/yosemitenationalpark?feature=watch

Sidewalk Astronomy tonight

by Jane Houston Jones

There will be telescopes out at the corner of Myrtle and Lime Streets tonight from sundown until about 9-9:30 p.m. depending on the crowds and the astronomers. So stop by for a great view of the moon, a last look at Jupiter until late fall, and maybe a peek at Saturn rising above the buildings. It should be a good night - the clear sky chart looks great! http://cleardarksky.com/c/MnrviaCAkey.html?1 Mojo and I are in Florida visiting family. We're planning to be with sidewalk astronomers here at Lakewood Ranch, near Sarasota, FL. But the clear sky chart indicates otherwise tho' (all those white squares indicate nothing but clouds and probably rain too) http://cleardarksky.com/c/HRHObFLkey.html?1 Here's a monthly recap of astronomical doings all year. http://jane.whiteoaks.com/2013/01/07/whats-up-in-2013-at-a-glance/ Here's our next dark sky public star party info. May 11 at Mojave National Preserve, Black Canyon Campground. There is free camping but RSPV is required as camping space is limited. RSVP with David Lamfrom at dlamfrom(a)npca.org or 760-219-4916 More info here: http://mojavepreserve.org/index.php/site/article/star_party_in_the_mojave_n… And if you are contemplating a getaway to Yosemite this summer, nearly every weekend (except full moon weekend) from July 4 through Labor Day there is an astronomy club doing a public star party at Glacier Point both Friday and Saturday nights -- as shown in this beautiful video: http://www.youtube.com/watch?v=ZhgR3zVfo-0&feature=youtu.be. The Northern California Astronomy Cubs choose their first, second and third choices for a weekend slot in a lottery. The club we always go with was granted August 22-23. Moon rises fairly early, so it is not the clubs first choice. But there will be dark skies for a few hours, a gorgeous view of Saturn, then moonrise near Half Dome through club members telescopes. Special announcement :-( Due to budget restrictions, plans for a JPL Open House in spring 2013 have been suspended. If budget considerations improve, JPL hopes to host an Open House at a future date, perhaps as early as fall 2013.

Telescopes tonight

by Morris Jones

We're going to have three telescopes set up tonight in old town Monrovia, Library Park, at the corner of Myrtle & Lime, starting about 7:00 p.m. The forecast is "mostly clear," and it looks like there might be a little marine layer fog rolling in, but we're hoping for the best. Jane and I are away from town this weekend, but wish them good luck! It should be a good night for the moon and Jupiter. Best regards, Mojo -- Morris Jones Monrovia, CA http://whiteoaks.com

A few telescopes out tonight

by Jane Houston Jones

Some of us are available tonight and some next week to do some sidewalk astronomy, so those of us available tonight will be at the corner of Myrtle and Lime Streets in Monrovia's Library Park tonight from 7 p.m. to about 9 p.m. If you are out for a stroll, stop by. We'll be looking at Jupiter and the moon through some marine layer haze, but if you are itching for some telescope viewing (like I am) come on down. Here is my first observation of Comet PanSTARRS - the current (barely) naked eye visible comet low in the west. http://jane.whiteoaks.com/2013/03/12/my-first-view-of-comet-panstarrs-31113/ About 25 minutes after sunset (at civil twilight) you may be able to spot the comet if you have good low western horizon and know where to look (not easy). It also helps to have a clear and dark sky (which we don't tonight). It is only about 10 degrees above the horizon (90 degrees is overhead). One of us may try moving a small telescope down Lime Street for a better view to the west, hoping for a little clearing between buildings and trees. I won't promise a view of the comet, but it is always fun to try! The window of viewing will be only from about 7:30 p.m. to 8:00 p.m. - probably even less time without a clear horizon. There are not only trees and buildings in the way, but hazy marine layer, too. I'll bring my binoculars and try to be optimistic. :-) Meanwhile here are some images of the comet: http://spaceweather.com/gallery/index.php?title=comet It's only been visible in the Northern Hemisphere for less than a week, and hopefully, it will still be around in April and May (though faint, and only visible in a telescope). But I hear it may be breaking up according to some if the imagers. Still, comets are so cool! -- Jane Houston Jones Monrovia, CA What's Up Podcast for March: Comet PanSTARRS, how bright?

That hard-to-find Comet PanSTARRS

by Jane Houston Jones

Have you looked up, scratched your head, and wondered where that "bright" comet is hiding? It's very challenging to see - and in binoculars it it is very small, as you can see in my sketches linked below. The circles represent the binocular field of view of either 5 or 7 degrees. The entire comet is about 1/2 of a degree long. Tonight, the 1 day old moon can be used as an arrow pointing to the comet, if you can find the slender Cheshire cat smile of a moon, that is. The moon will be found 5.6 degrees to the right of the comet tonight, and 10 degrees above the comet tomorrow night. Sunset tonight is at 6:57, and it will take about 25 minutes for the sun to set down 6 degrees, to the time called civil twilight - Evening civil twilight begins at sunset and ends when the geometric center of the sun reaches 6° below the horizon. Start scanning the sky about 8-10 degrees above the horizon at about 7:15, and keep looking until you either find the comet, or you don't. Here is my sketch of the comet from 25 miles up Angeles Crest (Chileo turnout) just before the Caltrans yard last night. This is a good spot facing west. http://jane.whiteoaks.com/2013/03/12/my-first-view-of-comet-panstarrs-31113/ and here is our Comet PanSTARRS resource page, which includes a good map and my "What's Up, PanSTARRS Edition" podcast. http://solarsystem.nasa.gov/scitech/display.cfm?ST_ID=2538 Happy comet hunting, everybody!

Spotting Comet PanSTARRS

by Jane Houston Jones

Mojo and I are going to our favorite observing location this afternoon, Amboy Crater, to try and view comet PanSTARRS just after sunset at 5:57 p.m. From now through the end of March, the comet should be naked-eye visible very low on the western horizon - low meaning about 10 degrees above the unobstructed horizon for those at latitude 40 (we are at 34 degrees North latitude here in the LA area), so it will be even a few degrees lower than that here throughout March. But it will be visible in April and May (through a telescope) higher and fainter in the sky. This month, use binoculars to scan the western horizon. Ten degrees can be measured by holding your clenched fist at arms-length distance, then with thumb-up, place the bottom of your fist on the horizon. The top of your fist (put your thumb back down first) will be ten degrees above the horizon. You'll see it's not very high. The comet's tail will be like your thumb up - because the tail will be pointing straight up. It's easy to see why -- comets tails point away from the sun. Any spot where you have an unobstructed view of the western horizon just at sunset is where you should look. Here in LA, looking west on the horizon generally means looking through a hazy (smoggy) or foggy layer of our atmosphere. The viewing window is just about a half hour after sunset right now - sunset until about 6:30 p.m. Longer window next week, but still very low. Watch my video for tips. Youtube: http://bit.ly/ZzW1bt You are welcome to join us - sorry for the late notice, we were waiting to see how the storm affected the deserts before deciding where and when to go. Amboy, CA 92304 is an unincorporated town in San Bernardino County, in California's Mojave Desert, west of Needles and east of Ludlow on historic Route 66. It is roughly 60 miles northeast of Twentynine Palms. Amboy Crater is a BLM landmark with a big parking lot. It takes us about 3 hours (including a sandwich stop in Barstow) to get there, and we'll arrive at about 4:30 p.m. to set up our equipment. It will be cold and windy tonight, so we plan to observe for about 4 hours then drive back home. It is not a campsite, so no tents, but you can sleep/rest in your car overnight and take a hike in the morning to the volcanic crater. There are pit toilets in the parking lot. We set up our two telescopes at the very end, next to the rest room. http://photo.whiteoaks.com/2011-10-22-amboy/Site%20Pictures/index.html If you do come, there are some universal courtesy tips to avoid blinding the observers. The San Jose Astronomical Association has a great list http://www.sjaa.net/etiquette.html To this list, most important is to arrive before sunset. It is virtually impossible to see the turnoff from Route 66 in the dark, and you will miss the comet hunt unless your are all ready to look at sunset. Park with your car lights pointed away from the telescopes closer to the entrance end of the lot. Switch your car's interior lights off if you can. We always bring some red carlight repair tape to place over very small flashlights, leave those big flashlights at home, you won't need them. No iPad, tablet, cell phones light near the (my) telescopes, please. Just step away and face your light away from the telescopes if you'd like to use them. They are fun to use, but will ruin (this) observer's dark adaption. Bring a chair, layers, binoculars, hydration. Oh there are trains with lights all night long, but I set up away from that light. You'll love to hear them in the dark. :-) Since this is short notice, you may want to consider joining us on May 11 at our campground star party at Mojave National Preserve instead. Hopefully, the comet will still be visible. The light pollution rules are a little more relaxed (except right near the telescopes) since it is a public star party. Last fall's flyer is here with directionshttp://mojavepreserve.org/index.php/site/article/star_party_in_th… If you do see the comet from LA let us know! Your chances are good if you can see the western horizon with no clouds or haze. Try with binoculars. We'll share what we see, how hard it was, tips and tricks tomorrow! Wish us luck!

You're invited to the Science Expo at Monrovia High School Saturday March 2

by Jane Houston Jones

Monrovia High School has been one of six schools in the nation chosen to host a downlink from the International Space Station this year! The downlink event will take place on Tuesday, March 5^th . All the 5^th graders and all the 8^th graders in MUSD will travel to the MHS Auditorium to be part of this amazing event! As the kick -- off for this event, MHS is hosting their first Science Expo tomorrow, Saturday March 2 10-2 p.m. and a star parety 6-8 p.m. This fun, free, public family event includes demonstrations from the Santa Fe Dam RC Modelers Club, UniTek lazers, FIRST Robotics, and GAVRT Radio telescope. Other booths will include glider making, Pinewood Derby and MHS Chess Club workshops, and information from the Deep Space Network, NASA/IPAC (CalTech Infrared Processing and Analysis Center) , the Planetary Society. The Sidewalk Astronomers will be sharing views of the sun through several different solar telescopes. Food will be sold, including hot dogs, pizza, and smoothies. This event will be on Saturday, March 2^nd in the MHS Quad from 10am to 2pm. You can stay later, and there wil be a star party from dusk until 8 p.m. The school address is 845 W Colorado Blvd Monrovia, CA 91016 In other news, I talk about the appearance of Comet PanStarrs in our skies beginning about March 10 through early May in my monthly video. The comet will be naked eye visible (somewhere between the magnitude of the bright star Sirius below Orion, and the dipper stars, but also extremely low to the horizon. An unobstructed view down to the horizon will be necessary - the comet will not get above 10 degrees above the horizon in March, higher but fainter in April and May. Binoculars will help you pull the comet out of the murky horizon.

sidewalk astro & more!

by Jane Houston Jones

There will probably be a few telescopes in Monrovia Saturday night (not Mojo and mine, we are on travel), and for sure a few other telescopes, including ours next weekend, weather permitting. The moon and Jupiter will be fabulous both weekends. No on to the email of many links: 2013 - monthly highlights - lots to look forward to this year!! http://jane.whiteoaks.com/2013/01/07/whats-up-in-2013-at-a-glance/ Asteroid flyby - explanatory video, some charts, and frequently asked questions: http://solarsystem.nasa.gov/scitech/display.cfm?ST_ID=2523 A few of the most asked FAQs: *Q: What is asteroid DA14* A: Asteroid 2012 DA14 is a small near-Earth object - approximately 150 feet (45 meters) in diameter. On Feb. 15, 2013, the asteroid will pass by our planet at a remarkably close distance, but the asteroid's path is understood well enough that there is no chance of a collision with the Earth. *Q: What date and what time will the asteroid be closest to Earth?* A: Asteroid 2012 DA14 will be closest to Earth on Feb. 15 at approximately 19:24 UTC (2:24 p.m. EST/11:24 a.m. PST). This time may change by a minute or two as the asteroid is tracked on its approach and predictions are refined. At the time of closest approach, the asteroid will be over the eastern Indian Ocean, off Sumatra -- approx. latitude: -6 deg South. / longitude: 97.5 deg East. These near earth asteroids are not very easy to spot in telescopes. This one will be extremely faint (as faint as Pluto at Magnitude 13 when in our night sky, moving swiftly past earth, about 10pm tomorrow night. Here is my tale of near earth asteroid watching - one in 2002,one in 2011 http://jane.whiteoaks.com/2011/11/10/watching-asteroids-fly-by/ Breaking news at 10:30 pm: I'll report more tomorrow when I see news and videos that have been verified, but seems a bolide exploded over Russia - Urals-city of Chelyabinsk -- Jane Houston Jones Monrovia, CA What's Up Podcast for Feb:Asteroid flyby, comet preview On Youtube: http://youtu.be/uEqt0yE6EG0 Twitter: http://twitter.com/jhjones /CassiniSaturn /otastro My Blog: http://jane.whiteoaks.com/ Yosemite Video http://www.youtube.com/user/yosemitenationalpark?feature=watch
