In other eclipses, the moon may seem to glow like a bright orange ember.The reason that the moon can be seen at all during totality is that sunlight is scattered and refracted around the edge of the Earth by our atmosphere.But many kinds of careful observations of a lunar eclipse can hold scientific interest.
The moon's passage through the Earth's shadow is presented for six time zones: one for Hawaii (HST), one for Alaska (AKST), and four across the U.
S and Canada: Pacific (PST), Mountain (MST), Central (CST) and Eastern (EST).
Such crater timings can be used to estimate the enlargement of Earth's atmosphere due to airborn dust and volcanic ash.
Even with the unaided eye, a lunar eclipse is pleasing to watch, but binoculars will certainly improve the view, though a small telescope is recommended. The beginning of a lunar eclipse happens simultaneously for every viewer, and the end will happen simultaneously for everyone, too. Hence, the simple schedule below holds for all places (the times differ only because of time zones).
During the 76 minutes that the moon is completely immersed in the Earth's dark umbral shadow, the big question will be how the natural satellite will appear in the sky.
Some eclipses are such a dark, blackish gray that the moon nearly vanishes from view.
30 was indeed a blue moon, that first full moon on Dec.
1, 1982, actually occurred on the previous day(Nov. Only for a few areas was the December 1982 total eclipse both visible and coincident with a Blue Moon: a section of eastern Asia (including Japan and Korea), Australia, New Zealand, and the Pacific Ocean west of the International Date Line.
This could help make the upcoming eclipse a relatively dark one.
A major eruption of this same volcano in 1963 caused the moon to almost completely vanish in an eclipse that December.
Another method is to time when selected craters are swept by the advancing shadow.
