Memory Management

The SSR has been emptying at the end of the passes set.

Spacecraft Status

Detectors 1, 3 and 8 are active and taking data. The cold plates 1 and 2 temperatures are 134.9 and 133.4, respectively. The cold tip/plate temperatures have increased slightly after turning on D1. The cryocooler power is at ~76.7W.

Data Gaps

There was no significant (>300s) data gap.

Detector issues

D1 was turned on, and it segmented at around 2860 V. It is now taking events. No threshold changes.

If the average of cold tip 1&2 temperatures reached 113, we will turn off D1.
