== Solar Activity ==<br />
<br />
The sun was moderately active this week. It hovered around a GOES B class background and had only some B and C class flares. There are 5 named active regions on disk<br />
<br />
How many GOES flares occurred?<br />
Flares above B, C, M, X class were 26 19 0 0<br />
And how many of these are listed in the RHESSI flare list?<br />
Flares above B, C, M, X class were 14 16 0 0<br />
And how many had EXCELLENT coverage?<br />
Flares above B, C, M, X class were 10 6 0 0<br />
<br />
There were RHESSI flares/GOES flares 158 / 45<br />
over the time range 05-Sep-12 12-Sep-12<br />
<br />
<br />
== Memory Management ==<br />
<br />
SSR had been reaching 40% early in the week, it emptied today. <br />
<br />
== Spacecraft Status ==<br />
<br />
Cold tip 1 and 2 are currently sitting at 91.6 and 89.8 K respectively. The cold plates are at 108.1 and 106.7 K respectively. Cryopower 71 W. <br />
<br />
Spin 14.7<br />
<br />
<br />
<br />
== Data Gaps ==<br />
<br />
The data from the data server failure last week has been recovered and filled in on Browser.<br />
<br />
<br />
<br />
== Detector issues ==<br />
<br />
D8 shows a long decay coming out of the SAA. This is affecting the livetime, the livetime is reduced to .8 and decays back to nominal at ~ 1/3 to 1/2 of the following orbit.<br />
<br />
There was discussion as to if lowering the voltage, or raising the threshold would be better to alleviate this problem. Raising the threshold would limit analysis of the iron line. It was decided to reduced D8 by 6 steps. <br />
<br />
== Other notes ==<br />
<br />
David Smith will report on the best detectors (at this time) for spectroscopy.<br />
