Solar activity this week was very low. There are not visible active regions on disk. STEREO-A images also indicate that there is no region expected to rotate onto the visible disk.
TIME RANGE:04-Apr-18 00:00:00.000 -- 11-Apr-18 00:00:00.000 % RD_WEEK_FILE: No input file for week 18_14 found in: $DIR_GEN_GEV % RD_WEEK_FILE: No input file for week 18_15 found in: $DIR_GEN_GEV No GOES flares for Time Range % Compiled module: CHECK_EXT_TIME. % HSI_QLOOK::GETDATA: No filenames found for this time range % HSI_QLOOK::GETDATA: Maybe you should update your SSW % HSI_TOHBAN_FLARE_COUNTER: No RHESSI Flare list for this time period % HSI_TOHBAN_FLARE_COUNTER: No RHESSI Flares for this time period
The SSR reached a maximum of ~94 percent during this week.
Detectors 3 and 8 are active and taking data.
The cold plate 1 and 2 temperatures are ~156.4K and 155.3K. As last week.
Currently the Cryocooler power is ~55 W and the acceleration is at ~11mg
Data was deleted on April 9 as the SSR fill level was very high. This move brought the SSR fill level down from 95% to 56% full. We skipped over data recorded from 2018-03-30 to 2018-04-01 ~11:30 UTC.
A spin down experiment is currently been make. The expectation is that reducing the mechanical stress on the s-band communication subsystem, stable communications with the spacecraft can be achieved.
The procedure started on 3 April 2018 at 23:00 UT. The spacecraft achieved 10 RPM on 4 Apr 2018.
