Tomorrow is the First SDO Lunar Transit of 2021

January 13, 2021, will see the Moon pass across the face of the Sun between 0556 and 0625 UTC (00:56 and 1:25 am ET). Here's a movie of the transit from the SDO Flight Operations Team.

This transit occurs while SDO is near the midnight sector of its orbit. That means the motions of the Moon and SDO combine to make this a short transit, lasting only about 30 minutes.
