SDO Weekly Report for July 22, 2011

On Wednesday July 20 SDO did two maneuvers, an EVE field of view from 1315-1600 UT and an HMI off point from 1630-1910 UT. During these maneuvers the near real time images look cut-off and some data may have been lost. An example of a shifted image is shown on the left. Unlike earlier maneuvers, where the image moved around in the picture, the NRT software is centering the image and we see the edge of the CCD as a straight line.

On 7/16 the MOC backup Real-Time system lost 3 hours of S-band data due to a line hit causing a socket disconnect. The primary string was unaffected so there was no impact.

We have been told that the electricity will be shut off in the room with the Goddard SDO computers this weekend. This means the website will be down from 6:00 am to as late as 3:00 pm ET. The instrument websites are not affected by this outage and neither is the satellite. Sorry for the inconvenience.
