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!
