Solar and lunar Eclipse Dates for 2012

May 20, 2012: Annular eclipse of the Sun This rare eclipse will be partially visible from all but eastern North America. For most western locations, the eclipse will begin between 5:00 P.M. and 6:00 P.M. PDT. In Alaska and parts of northern Canada, the eclipse will start an hour earlier and end 2 to 3 hours later (or will be interrupted by sunset). In San Francisco, for example, the eclipse will begin at 5:16 P.M. PDT, reach its maximum at 6:33 P.M., and end at 7:30 P.M., with the Sun very low on the horizon.

June 3-4, 2012: Partial eclipse of the Moon In North America, this will be fully visible only from western Alaska; Hawaiians will also have a view. The Moon will enter the penumbra at 10:47 P.M. HAST on June 3, reach a maximum at 1:03 A.M. on June 4, and then leave the penumbra at 3:20 A.M. The eclipse will be partially visible from most of central and western parts of North America; observers will be able to see both a penumbral and umbral eclipse. The Moon will enter the penumbra at 1:47 A.M. PDT on June 4 and then enter the umbra at 2:59 A.M. PDT. However, the Moon will set before completion of the eclipse. Only a penumbral eclipse will be visible from the Northeast, starting at 4:47 A.M. EDT on June 4, before the Moon sets.

November 13-14, 2012: Total eclipse of the Sun This eclipse will not be visible from North America. It will be visible only from Australia, Polynesia, the South Pacific Ocean, southern South America, and Antarctica.

November 28, 2012: Penumbral eclipse of the Moon This eclipse will be fully visible only from Alaska and western parts of Hawaii. The Moon will enter the penumbra at 3:13 A.M. AKST, reach a maximum at 5:33 A.M., and exit the penumbra at 7:53 A.M. In central and western North America, the eclipse will begin at 4:13 A.M. PST, but the Moon will set before the eclipse concludes. No eclipse will be visible from eastern North America.
