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
On Feb. 26, the temperature threshold for the HV cutoff was changed from 100K to 115K, with yellow and red limits put in at 105K and 110K, respectively. This was done to ensure that we do not trip the cutoff since the temperature is now just below 100K. (CP2 is currently at 97.6K.) However, it does appear the the temperatures have recently been trending downward.
A HV change was requested: another 6 steps down on detectors 6 and 8.
