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.
. 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.:-)
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.
