8:26 pm - another ISS pass tonight, Perseids are peaking too!

There was a great ISS pass Tuesday night -- we watched it from the Hollywood Bowl at intermission of Star Wars: A New Hope, in concert with LA Phil orchestration, and the film on the big screen. Folks at the "bowl" tonight will see the same show, including A New Pass! Time: Fri Aug 10 8:26 PM, Visible: 4 min, Max Height: 82°, Appears: 36° above NW, Disappears: 13° above SE. To get your own email or text alerts of passes over your location just sign up here https://spotthestation.nasa.gov/ Now about the Perseids. The rates have been increasing day by day, just as predicted. You can see the last few years Perseids rates in my August what's Up video. https://www.facebook.com/NASAWhatsUp/ or at the other usual places. The Perseids, in a nutshell are visible at rates over 20 per hour for a couple weeks. The "peak" where the rates go up to 50-60 per hour (fewer seen from areas with light pollution, smoke, or clouds) and more -- up to maybe 70 per hour -- from the very darkest locations. Sunday night is the "peak" bur Friday, Saturday and Monday nights should also be well above the 20 visible per hour last night. This great chart shows the work of "citizen scientists" who go out and rigorously count meteors around the world. Bookmark and check back if this interests you. http://www.imo.net/members/imo_live_shower?shower=PER&yea=2018 The citizen scientists use a standard set of tools: Eyes, comfy chair, pencil, clipboard, tape recorder sometimes, timepiece that doesn't emit light to keep track of timed observing intervals, some star charts to measure your own visual acuity and sky darkness -- to see how many stars you can see in a triangle of fairly bright stars -- you might only see the three bright anchor stars from the city, you may see 5 to 30 from a dark site. With all these tools, even an observation from light polluted LA county (my driveway) matters, and the fact that I may only see a few per hour, in miserable light pollution, is calculated and part of the data. If this interests you, I'll be happy to drag some of you out to Amboy crater or another dark location of my choosing to count meteors and submit your data. It's geeky science fun!
