The SSR level has been toggling around 25%. It reached a minimum of ~5% and the maximum of ~35%.
Detectors 1, 3, 6 and 8 are active and taking data.
The cold plate 1 and 2 temperatures are ~157.2K and 155.3K. The shadow length will reach its relative minimum on Nov. 25.
Currently the Cryocooler power is ~75 W and the acceleration is at ~11mg.

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:
%deadtime attnuator state 0.00 Min A0 30.98 Max A0 <--Thin in 27.45 Min A1 <--Thin out 32.94 Max A1 <--Thick in 26.67 Min A2 40.78 Max A2 28.24 Min A3 <--Thick out 100.00 Max A3
A software issue with D6 spectrograms was fixed and the data are now being reprocessed.
