How To Watch the 'Super Blue Blood Moon' Lunar Eclipse (livescience.com)

Stephanie Pappas reports via Live Science how you can watch Wednesday's "Super Blue Blood Moon" eclipse: The eclipse will occur in the wee hours of the morning on Wednesday, Jan. 31, when the full moon will pass through the Earth's shadow. Viewers on Earth will see the face of the moon turn a murky red. On the West Coast, totality (the full shading of the moon) will occur at 4:51 a.m. PST until 6:08 a.m. PST. Before that, the moon will enter the outer portion of the Earth's shadow, or penumbra, at 2:51 a.m. PST. The real show will become visible starting at 3:48 a.m. PST, when the moon will be entering the umbra, or central portion of Earth's shadow, and a dark shadow will move over the face of the moon. The moon will leave the umbra at 7:11 a.m. PST. East Coasters can catch the partial lunar eclipse before dawn, but they will miss totality because the moon will have set below the horizon by 7:06 a.m. EST. To see the shadow of the Earth become visible on the moon's face, look up at 6:31 a.m. EST; by 6:48 a.m. EST, the moon will be entering the umbra, or central portion of the shadow, which should make the color change more apparent.

For viewers in the Central and Mountain time zones, the moon will set either during the total eclipse or while the satellite is exiting the Earth's shadow. The moon enters the dark umbra at about 5:48 a.m. CST and will hit totality slightly before moonset, at 6:51 a.m. CST. The umbra will appear at 4:48 a.m. MST, and the moon will enter totality at 5:51 a.m. MST. Viewers in the Mountain time zone will also get the chance to see the middle of totality, when the moon is up to 100,000 times fainter than usual, at 6:29 a.m. The eclipse will end slightly before moonset, at 7:07 a.m. MST. Viewers in Alaska and Hawaii will get a full dose of totality, too, but they'll have to be very early birds or night owls. Totality begins at 3:51 a.m. AKST and ends at 5:05 a.m. AKST. Totality hits at 2:51 a.m. HST and will be over by 4:05 a.m. HST.

  7. What's with all the stories about the moon? by imidan · · Score: 2

    What's the deal with all the stories about the moon in recent months? Blue moons, super moons... a blue moon is a second full moon in a calendar month. Other than the arbitrary coincidence of the lunar cycle going from full moon to full moon within a named period of time, there's absolutely nothing interesting or unique about it.

    The "super moon" is apparently a full moon near the moon's perigee appearing "up to 14 percent larger and 30 percent brighter than usual." I guess that could be interesting, maybe to photographers? I don't personally notice that much difference. Maybe if I could see the super moon and the regular moon side-by-side in the sky...

    Last year there was a news story about the "strawberry moon" which is apparently a name for a full moon that happens in June. Since the lunar cycle is about 29.5 days, and June is 30 days long, there is necessarily a full moon in June every year.

    I don't want to shit on "science" things that are fun and interesting, but I mean... does the appearance of the moon qualify? What is this about? I don't remember these articles always popping up when I was a kid.
