Sidewalk Astronomy this weekend, and Intl Space Station on Saturday

I'm delighted to see that our recent monsoon moisture is drying out a little, and conditions should be warm but less humid than earlier this week. Tonight we plan to be in Old Town Pasadena, on Colorado Blvd. near Delacey from about 7:30 'til 10:00. We should have great views of the first quarter moon and Jupiter tonight. Jane's most recent "What's Up" video from JPL is all about Jupiter this month, and a great preview to help interpret what you can see in a telescope: http://www.jpl.nasa.gov/videos/whatsup/whatsup20080808/ Tomorrow night (Saturday) should have similar weather, and we'll be at our usual spot in Old Town Monrovia. Saturday evening features a nice nearly overhead pass of the International Space Station at about 8:10 p.m., just about 25 minutes after sunset. The ISS is so big and bright now, it should be easily visible even in the evening twilight, though almost no stars will be visible that early. The station will appear at about 8:10 above the northwest horizon, well to the right of the glow of the sunset. Venus may still be visible just above the horizon, setting due west. The ISS will pass almost overhead by 8:12, passing the bright orange star Arcturus, and will disappear in the southeast, passing bright Jupiter, by about 8:15. Hope you can join us this weekend!
