Memory Management

The SSR was empty at the end of each set of daily passes, until 2014-04-08. Currently SSR is at 25%, due to extra aspect data. Decimation is active/vigorous.

Spacecraft Status

The cold plates, 1 and 2 were at 116.9 and 155.5 K, on 2014-04-07.

Data Gaps

Dropped 1 App_id = 102 packet on 2014-04-03

Detector issues

Live time on G6 is very low, at about 3% for the most recent data, 2014-04-09 08:00. On 2014-04-07, G6 HV was decreased by 10 steps, and the live time increased, but all gains have been lost.

Other notes

On 2014-04-08, aspect data time resolution was increased for observations to be coordinated with an SDO calibration. Th special ATS was loaded on 2014-04-07, and implemented on 2014-04-08.
