== Solar Activity ==<br />
<br />
Solar activity this week was moderate with a number of C class flares. There was also an M2.5 class flare from an unnumbered active region on the south east limb in the last few hours. There are currently 6 active regions on disk, with a moderately high background at GOES C1 level. STEREO B shows a few active regions which will rotate onto the disk in the next week.<br />
<br />
How many GOES flares occurred?<br />
Flares above B, C, M, X class were 12 38 0 0<br />
And how many of these are listed in the RHESSI flare list?<br />
Flares above B, C, M, X class were 7 27 0 0<br />
And how many had EXCELLENT coverage?<br />
Flares above B, C, M, X class were 6 11 0 0<br />
<br />
There were RHESSI flares/GOES flares 271 / 50<br />
over the time range 27-Aug-14 03-Sep-14<br />
<br />
== Memory Management ==<br />
<br />
The decimation state this week was normal/vigorous and data was being collected in both the front and rear segments during eclipse in order to record data during the thunder storm season for David's TGF research. The SSR is currently reaching around 40%, with a minimum of around 25% at the end of the daily pass set. The decimation state was raised today (3-sep-2014) and extra Weilheim passes are scheduled to downlink the data. <br />
<br />
== Spacecraft Status ==<br />
<br />
The segmentation status has not changed, with 1,3,8, and 9 stably segmented and D6 segmented most of the time, but losing segmentation during/following SAA passages. This segmentation is expected to become more stable over time.<br />
<br />
== Data Gaps ==<br />
<br />
There were no data gaps.<br />
<br />
== Detector issues ==<br />
<br />
Detector 9 showed 2 short periods of noisy data within the last 48 hours. No action was taken to lower the HV on detector 9. The next tohban should keep an eye on this. <br />
<br />
The effects of the light leak in detectors 2 and 3 remaining mostly unchanged despite raising the fast thresholds for these detectors on the 29th of August 2014. Tohban's should continue to monitor the situation. Raising the thresholds further may introduce difficulties when analyzing the data, therefore it was decided to leave the system in its current state.<br />

<br />
== Spacecraft Operations ==<br />
<br />
<br />
On August 26 (DOY 238) the following threshold changes were made:<br />
* G2 front fast was raised from 0x38 to 0x40<br />
* G3 rear fast was rasied from 0x50 to 0x60<br />
