SDO images look partial today as we are off-pointed to look for the tail of Comet C/2025 S1 (ATLAS) as it goes by perihelion. This is a Kreutz comet with a perihelion distance of 1.7 Rsun (0.7 Rsun above the surface of the Sun.) The perihelion time as seen at Earth is about 11:45 UTC (7:45 UTC). We will hold the offpoint until 12:05 UTC and then return to normal pointing. HMI magnetograms and Dopplergrams are not available during the offpoint.
