== Solar Activity ==<br />
<br />
The Sun was fairly active and region 12665 produced a series of flares.<br />
In particular, 2017-07-14, a long duration M-class flare has been observed<br />
where RHESSI covered most of the impulsive phase including the peak.<br />
<br />
TIME RANGE:12-Jul-17 00:00:00.000 -- 19-Jul-17 00:00:00.000<br />
Flares above B, C, M, X class were 31 24 1 0<br />
<br />
How many GOES flares occurred?<br />
Flares above B, C, M, X class were 31 24 1 0<br />
And how many of these are listed in the RHESSI flare list?<br />
Flares above B, C, M, X class were 16 11 1 0<br />
And how many had EXCELLENT coverage?<br />
Flares above B, C, M, X class were 12 4 0 0<br />
<br />
There were RHESSI flares/GOES flares 120 / 56<br />
over the time range 12-Jul-17 19-Jul-17<br />

== Memory Management ==<br />
<br />
Decimation was active/vigorous for the full time period, with the SSR level currently at around 30%.<br />
<br />
== Spacecraft Status ==<br />
<br />
Detectors 1, 3, 6, and 8 are recording events. The cold tips are about 128K as of July 19, and cold plates are at about 153K. <br />
Cryocooler power is steady at 75.6W, for recent tmperatures, cryocooler efficiencies, and accelerometer values see:<br />

<br />
== Data Gaps ==<br />
<br />
None known.<br />
<br />
== Detector issues ==<br />
<br />
Detectors 1, 3, 6, and 8 are powered on, and are recording events. No detector operations this week.<br />

<br />
== Notes ==<br />
<br />
On 2017-194-19:50:11 UTC (July 13, 2017),<br />
the attenuator thresholds were changed, to reflect a new background of 17.1% deadtime.<br />
