Photos of last night’s eclipse, plus tonight’s moon near Aldebaran
For us in North America, the November full moon is the Beaver Moon or Frosty Moon. In the Southern Hemisphere, where it’s the opposite time of year, the November full moon is a fixture of the spring season. For all of us, this November 2020 full moon shines directly in front of the constellation Taurus the Bull. It’s the third and final full moon of this Northern Hemisphere autumn or Southern Hemisphere spring.
We in North America were well placed to view last night’s partial penumbral eclipse of this full moon. Some photos are below.
It was the faintest of eclipses – nearly imperceptible – so that some of you would swear nothing was happening even while staring straight at it. Then again … observant people, like Nils Ribi, whose photo is above, did notice a subtle shading on the moon.
You had to be on the nighttime side of the Earth while the eclipse was taking place or you’d miss it altogether. We refer you to the worldwide map below showing the day and night sides of Earth at the instant of greatest eclipse.

At best, the eclipse might be visible to the eye for roughly an hour, centered on the greatest eclipse (mid-eclipse). We give the time of the greatest eclipse for United States time zones:
Eastern Standard Time (EST): 4:43 a.m. (November 30)
Central Standard Time:(CST): 3:43 a.m. (November 30)
Mountain Standard Time:(MST): 2:43 a.m. (November 30)
Pacific Standard Time (PST): 1:43 a.m. (November 30)
Alaska Standard Time (AKST): 12:43 a.m. (November 30)
Hawaii Standard Time (HST): 11:43 p.m. (November 29)
We give the times for the beginning and ending of the penumbral eclipse in Coordinated Universal Time (UTC). Be mindful, however, that the eclipse won’t be visible to the eye until the moon’s disk is about 2/3 submerged in the penumbral shadow:
Penumbral eclipse begins: 07:32 UTC (November 30)
First visible?: 09:10 UTC (November 30)
Greatest eclipse: 09:43 UTC (November 30)
Last visible?: 10:10 UTC (November 30)
Penumbral eclipse ends: 11:53 UTC (November 30)
Although the moon actually looks full to the eye for two or three days in a row, the moon is astronomically full for only an instant – when it’s 180 degrees opposite the sun in ecliptic longitude. At full moon, the sun-moon elongation equals 180 degrees. Visit Unitarium.com to know the present elongation of the sun and moon, remembering that a positive number means a waxing moon and a negative number a waning moon.
Since the moon stays more or less opposite the sun throughout the night at the vicinity of full moon, look for the moon (and the constellation Taurus) to rise in the east around sunset, climb highest for the night around midnight and set in the west around sunrise.
Because the full moon resides opposite the sun in the northern constellation Taurus the Bull, the full moon’s path across the night sky will resemble that of the sun in the daytime sky for six months hence. In late May, the sun resides in the constellation Taurus, well to the north of the Earth’s equator. For both the Northern and Southern Hemispheres, that means this northerly full moon will rise and set considerably north of due east and west. Therefore, for the Northern Hemisphere, this late November full moon will mimic the high path of the late May springtime sun; and in the Southern Hemisphere, it’ll imitate the path of the late May autumn sun.
Bottom line: We in North America were well placed to view a partial penumbral eclipse of the November 2020 full moon on the night of November 29-30. Eclipse photos here.
