Contents

Solar Activity

Solar activity was really low this week. Currently there are four very little active regions on the disk with very low probability to host big flares. Three of them are rotating off of disk in the next couple of days. Solar activity is expected to be low next days.

Memory Management

The SSR fill level continued high most of the week but during last couple of days has shown a good decrease. Currently SSR reaches a maximum of around 30% and is emptying at the end of daily passes.

Spacecraft Status

Normal as far as the Tohban can tell.

Data Gaps

No data gaps this week

Detector issues

On May 21 starting at 19:23 UTC we made a few changes to detectors 2, 4 and 6. We raised thresholds on the Front Slow on all of them as follow:

Threshold [G2] Front Slow
Initial 0x50
Final 0x58


Threshold [G4] Front Slow
Initial 0x60
Final 0x70


Threshold [G6] Front Slow
Initial 0x15
Final 0x20


In addition, yesterday (May 26) starting at 19:11 UT we lowered the HV on detector 6 by 30 counts as follows:

G6 High Voltage
Initial 133 2573 V
Final 103 1985 V

Other notes

Decimation Normal/Vigorous
Night time data (fronts) No nighttime events
Night time data (rears) No nighttime events
Require extra passes? No
Requirement for moving pointer? No
Attenuator operation Normal
