Total lunar eclipse tonight!


Well, late tonight or early tomorrow morning. Penumbra starts at 2:15 am tonight, totality begins at 4:25 am and ends at 5:25 am, and dawn will break before the moon is fully out of the earth’s shadow next morning!

This is the second “blood moon” of the four happening this year and next, approximately one occurring every six months. So if you miss this one, just catch the next one in the spring!

The moon really will turn red during totality, as seen from the above photos from last spring’s lunar eclipse. The reason is that Earth’s apparent size is so much bigger than the sun from the perspective of the moon, but our atmosphere refracts the sun’s light to the moon so that it appears like the moon is seeing every sunset on Earth at the same time! And we see that reflected sunset light here.

For those of you in and around Jackson, if you can, GO CAMPING TONIGHT ON SHADOW MOUNTAIN!!! The angle of the setting, blood-red moon from there will be such that it will appear over the saddle between the Grand and Middle Tetons.
