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.

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.

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@

Over and out, Jane
