The skies over Monrovia are covered with marine layer right now. The skies at Mount Wilson, on the other hand, are clear, sort of. Take a look at the Mt. Wilson 150-foot towercam, and you'll see clear skies at the peaks, but creeping marine layer almost reaching to the observatory. http://obs.astro.ucla.edu/towercam.htm#imagetop So, sadly, we're cancelling Sidewalk Astronomy tonight. Next Saturday night, is a not-quite-full-moon, and we'll tentatively reschedule for that night -- Saturday, October 27th, 6:30-9:00 p.m. This cloud layer will also wash out meteor watching overnight, too, most likely. The forecast calls for a slight chance of drizzle after 8 p.m. Some of our astronomers will be heading east to catch some shooting stars. If you are so inclined, take a look at all these astronomers maps - the Clear Sky charts, and head for an area not showing white in the hourly grids - those indicate cloud cover. http://cleardarksky.com/csk/prov/California_charts.html Finally, since it's an indoor-stargazing and meteor-gazing kind of night, here's a writeup about the huge meteor (probably a small asteroid, actually) that broke up over northern California last Wednesday night. There were reports from Long beach to Red Bluff, with a sonic boom and a terminal burst - like a roman candle as the meteor broke up into pieces. It broke up over Marin County, where I grew up! Dr. jenniskens is out looking for dark pieces this weekend. if you find one, take a picture and send it to him by email petrus.m.jenniskens <http://petrus.m.jenniskens>@ nasa.gov Over and out, Jane -- Jane Houston Jones Monrovia, CA What's Up Podcast for Sept: Observe and wink at the moon On Youtube: http://is.gd/kPUtSx Twitter: http://twitter.com/jhjones /CassiniSaturn /otastro My Blog: http://jane.whiteoaks.com/ Yosemite Video http://www.youtube.com/user/yosemitenationalpark?feature=watch
