Eclipse times (Score 1)

Since no one seems to have posted these details, the umbral phase of the eclipse, which is the fun part to watch, begins at 3:01 UT on the 21st (= 7:01 p.m. PST, 10:01 p.m. EST on the 20th). The eclipse is total from 4:05 to 5:22 UT (= 8:05 to 9:22 p.m. PST, 11:05 p.m. to 12:22 a.m. EST). The umbral phase ends at 6:26 UT (= 10:26 p.m. PST, 1:26 a.m. EST). The Moon is in the penumbra (where the Earth only partly covers the Sun as seen from the Moon) about two hours longer, but this is difficult to detect. I strongly recommend not waiting for totality to look. The partial phases add a lot to the drama.

One note regarding the July 16 eclipse: though the partial phases will be visible throughout much of the western U.S., only those on the coast of California will witness totality, and only for a few minutes at most before moonset.
