The SSR reached a maximum of ~53 percent during the week. Currently is about ~30 percent.

Spacecraft Status

Detectors 1, 3, 6 and 8 are active and taking data. The cold plate 1 and 2 temperatures are ~155.6K and 154.0K.

Decrease the attenuator threshold to 12.5% deadtime.

Currently the Cryocooler power is ~74.9 W and the acceleration is at ~11mg

Data Gaps

No VC3 data gaps this week.

Detector issues

Detector 6 show high fast front counts during the week, however in the last days it auto-correct itself.

Other notes

PMTRAS saturation due to the lost of WLP passes, leading to about 2 hours of data lost.
