SDO Views Comet ISONOn November 28, 2013, the SDO (Solar Dynamics Observatory) spacecraft will off-point at three different positions as Comet ISON moves through perihelion. This website will display near realtime images and movies of this sungrazing comet. Images should begin appearing sometime between 12:45 pm and 1:00 pm ET.
Images from SDO take about 6 minutes to move from the spacecraft to our computer at Goddard. We plan to off-point at 17:30 UTC (12:30 pm ET) and return to normal solar observing at 20:45 UTC (3:45 pm ET). We will begin posting images after SDO completes the first repointing maneuver and we obtain and process the data. Images should begin appearing sometime between 12:45 pm and 1:00 pm ET.
