== Solar Activity ==<br />
<br />
Solar activity this week was very low. There is only one active region on disk. Solar activity is expected to continue at low levels.<br />
<br />
How many GOES flares occurred?<br />
Flares above B, C, M, X class were 5 0 0 0<br />
And how many of these are listed in the RHESSI flare list?<br />
Flares above B, C, M, X class were 2 0 0 0<br />
And how many had EXCELLENT coverage?<br />
Flares above B, C, M, X class were 1 0 0 0<br />
<br />
There were RHESSI flares/GOES flares 2 / 5<br />
over the time range 14-Nov-17 21-Nov-17<br />
<br />
== Memory Management ==<br />
<br />
The SSR level has been toggling around 25%. It reached a minimum of ~5% and the maximum of ~35%.<br />
<br />
== Spacecraft Status ==<br />
Detectors 1, 3, 6 and 8 are active and taking data.<br />
<br />
The cold plate 1 and 2 temperatures are ~157.2K and 155.3K. The shadow length will reach its relative minimum on Nov. 25. <br />
<br />
Currently the Cryocooler power is ~75 W and the acceleration is at ~11mg. <br />

== Detector issues ==<br />
<br />
The attenuator thresholds were increased to account for a background deadtime of 26% deadtime on G3 (at 2017-319-22:05 UTC). The thresholds are as follows:<br />
<br />
%deadtime attnuator state<br />
0.00 Min A0<br />
30.98 Max A0 <--Thin in<br />
27.45 Min A1 <--Thin out<br />
32.94 Max A1 <--Thick in<br />
26.67 Min A2<br />
40.78 Max A2<br />
28.24 Min A3 <--Thick out<br />
100.00 Max A3<br />
<br />
== Other notes ==<br />
<br />
A software issue with D6 spectrograms was fixed and the data are now being reprocessed. <br />
<br />
