To add insult to injury tonight, there is an ISS pass at 5:56 p.m. Pacific (Southern California only). It will appear 10° above SW horizon. Visible for 5 minutes, it disappears 26° above NE horizon. Maximum height is 79°. You can get your own ISS alerts here, by signing up at NASA's Spot The Station website. https://spotthestation.nasa.gov/ Another fun and free tool is Heavens Above, a website/App where you can find flyover data on many additional satellites, and check after the fact to verify something you saw. https://www.heavens-above.com/ A final astronomers resource for both light pollution data and cloud cover is the Clear Sky Chart. Here is the list of the many California charts, so you can see if your particular area will be more cloudy or less cloudy tonight or anytime. https://www.cleardarksky.com/csk/prov/California_charts.html.  Click on a category such as "Cloud Cover" to get a great explanation. You might find it useful to check out sky conditions when you'll be traveling, vacationing. You might even find a great dark sky location or astronomy club you didn't know about! There are hundreds of charts for each state in the US, all the Canadian provinces, Mexico and even the Bahamas.:-) https://www.cleardarksky.com/csk/index.html#chart_list Our forecast is still for marine layer tonight, but I'll be out hoping to catch some ISS views early and Eclipse views later. Let me know if you luck out. -- Jane Houston Jones, retired JPLer Twitter: @jhjones @otastro Instagram @janehoustonjones http://www.otastro.org/ Astronomy,travel,music,food,cats
