Solar Activity
Very calm: the GOES LO channel was flat-lined the whole week. A weak active region (AR 11014) appeared in the middle of the week, but did not amount to anything interesting X-ray-wise.
Memory Management
Max SSR fill is 20-25%, goes down to 0% at the end of each daily pass set. The decimation is normal/active and front-segment events are being recorded during eclipse.
Data Gaps
On March 4, there are a few 5 or 10-mins gaps. Another one on the 5th, and two more on the 7th. Given the Sun's inactivity, it is probably not worht replaying them.
Spacecraft Operations
Cold Plate 2 is 0.2 K warmer than last week.
Email from Jeremy on 2009/03/05:
Today, between 064-21:43 UT and 065-01:20 UT we spun up to 15.00 RPM. We also lowered the voltages on detectors 6 and 8 by 6 steps as discussed in the meeting yesterday. The exact time of the HV commanding was:
09-064-23:20:12 /ihvdac detector=6, voltage=109 09-064-23:20:38 /ihvdac detector=8, voltage=113
Detectors 6 and 8 remained segmented.
