Memory Management

The SSR is emptying at the end of each pass. We remain in normal/active decimation mode.

Data Gaps

One data gap from 27th to 28th (21:20-01:45) due to network firewall issues.

Spacecraft Status

Due to magnetic anomalies RHESSI entered idle mode at 2011-05-01 16:30 UTC and began to drift off sun pointing. Commands were sent to enter precession mode at 2001-05-02 04:45 UTC and we returned to normal mode by 2011-05-02 07:45 UTC. This occurred again on 2001-05-02 between 09:51:16 and 23:44:02 and was once again corrected for.
