Solar Activity
Solar activity was very low during the week.
How many GOES flares occurred?
Flares above B, C, M, X class were 1 1 0 0
RHESSI flare list contains 0 over the time range 06-Jun-18 13-Jun-18
No overlapping RHESSI flares to count, sorry
Memory Management
The SSR is probably full by today, because of the anomaly.
Spacecraft Status
All detectors are offline
No info--- on Temperatures
The cold tip 1 and 2 temperatures are ~171.8 and 170.1 K.
Currently the Cryocooler power is ~52 W and the acceleration is at ~21mg.
Data Gaps
= Detector issues

Spacecraft Management
During this week the cryocooler power was increased from 46W to 52W. Soon after the power increase, communications with the spacecraft became difficult resulting in the total loss of commanding capability. The ATS ran out at 161-23:23:59 UTC, which means that RHESSI will no longer turn on the transmitter, for scheduled contacts and blind acquisition won't work without an uplink. After the spacecraft goes four days without receiving a command, it will run an RTS which will power off the cryocooler. At that point, the receiver should cool enough to get some commands in.
