Solar Activity
Solar activity was relative low with only 1 M class flare. There are currently 7 ARs on the disk, 2 are rotating off. There is 1 AR that has rotated on disk a couple of days ago, but it hasn't produced any major flare yet.
There were RHESSI flares/GOES flares 345 / 40 over the time range 23-Dec-14 30-Dec-14
Memory Management
Decimation was changed from Active/Vigorous to Normal/Vigorous. There were no changes on night time event collection this week.
Spacecraft Status
Data Gaps
There was no significant data gap.
Detector issues
On January 5 at 14:57 UTC, we changed thresholds on the front fast and front slow values for G5.
| Threshold | Front Fast | Front Slow |
| Initial | 0x60 | 0x80 |
D5 has largely segmented over the past week. The next tohban should try to lower the front threshold.
The other detectors are stable, 2 and 4 are unsegmented.
Light leak in D2 front, D9 rear and D5 rear.
Other notes
Spacecraft Management
| Decimation | Normal/Vigorous |
| HLAT Decimation | Rear decimation weight 6, no front decimation |
| Night time data (fronts) | +/- 4 minutes |
| Night time data (rears) | full nighttime events |
| Require extra passes? | No |
| Requirement for moving pointer? | No |
| Attenuator operation | Normal |
| Detector problems? | D2 front and D9 rear light leak. |
