Spacecraft Status

The spacecraft decimation mode was change to active/vigorous on 089/18:42 UTC (March 30), we are taking data 4 minutes on each side of the eclipse.

At the moment a RHESSI-SDO coordinated operation is been undertaken, ending at about 12:00 PDT on 06 April 2011. During the operation the SSR filling has increased to 46%.

On March 31st an unusually strong arc with a long response was observed in detector 6.
