Ephemeris: 08/27/2026 – Nearly total lunar eclipse visible tonight

August 27, 2026 Leave a comment Go to comments

his is Bob Moler with Ephemeris for Thursday, August 27th. Today the Sun will be up for 13 hours and 28 minutes, setting at 8:28, and it will rise tomorrow at 7:00. The Moon, 1 day before full, will set at 7:25 tomorrow morning.

Late tonight and into tomorrow morning, clouds permitting, we will be able to see a partial eclipse of the moon. The moon will be almost totally immersed in the earth’s umbral shadow, with only a tiny sliver of the top of it visible at maximum eclipse. The partial eclipse starts at 10:34 PM EDT. The maximum of eclipse will be at 12:13 AM, and it will end at 1:52 AM. So it will be great viewing for those who can stay up late to see it. The moon will pass through the northern part of the earth’s shadow and since about 93% of the moon’s diameter will be immersed, the reddish appearance of the moon in the shadow might be apparent to the naked eye, and should be apparent in binoculars. The dusky appearance of the moon may appear half an hour before and after the eclipse. Use sunglasses to make the penumbral shadow easier to see.

The astronomical event times given in this blog are for the Traverse City/Interlochen area of Michigan (Lat 44.7° N, Long 85.7° W; EDT, UT – 4 hours) unless stated otherwise. Times will be different for other locations.

Addendum

Preview of the partial lunar eclipse on the night of August 27-28 2026. The orientation of the moon and earth’s shadow is that for the naked-eye or binoculars. The motion of the moon in the sky during the eclipse is east to west (left to right) due to the earth’s rotation. However, the moon’s motion against the stars and with the earth’s shadow is west to east (right to left). The times are for the beginning maximum and end of the partial phase. EDT is 4 hours behind Universal Time. Created using Stellarium.
