Sunday morning OPs Day Shift Start

TITLE: 01/14 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 153Mpc
OUTGOING OPERATOR: Ryan S
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 5mph Gusts, 3mph 5min avg
    Primary useism: 0.03 μm/s
    Secondary useism: 0.28 μm/s
QUICK SUMMARY:
When I walked in H1 was in OBSERVING for 4 hours, but we had reasonably large 500hz Violin spike on darm, and the DCPD's were diverging.
I quickly checked the Violins, and noticed that the ITMY Mode 5 seting was in it's Nominal Gain state of +0.02 and was rising again.
Changed the Gain back to -0.02 and it has already turned around and started to fall.

Im not sure what is going on with  temperature senors looks like there was a rest or something but the temps all seem to be "Frozen" or not changing like they normally do.
I dont see any CDS errors about this, and it doesn't seem to be mentioned in the alogs. So tagging FMCS and documenting the temps are they currently stand.

CS: Everything looks good in the LVEA all green. 
H0:FMC-CS_LVEA_ZONE1B_DEGF= 67.4
H0:FMC-CS_LVEA_ZONE2A_DEGF= 66.79
H0:FMC-CS_LVEA_ZONE3A_DEGF = 67.3
H0:FMC-CS_LVEA_ZONE4_DEGF =67.7
H0:FMC-CS_LVEA_ZONE5_DEGF =67.3

EX Some temp channels are RED:
H0:FMC-EX_VEA_202A_DEGF = 57.40 RED
H0:FMC-EX_VEA_202B_DEGF =68.5 green
H0:FMC-EX_VEA_202C_DEGF =68.3 green
H0:FMC-EX_VEA_202D_DEGF = 58.70 RED
H0:FMC-EX_VEA_AVTEMP_DEGF = 64.73 green

EY:
H0:FMC-EY_VEA_202A_DEGF = 61.7
H0:FMC-EY_VEA_202B_DEGF = 67.40
H0:FMC-EY_VEA_202C_DEGF = 67.6
H0:FMC-EY_VEA_202D_DEGF = 59.9 RED

Since this morning, I've tried, restarting the ndscope, and the nuc.
And slowly figured out that its not an FMCS error.
Also I stand corrected I didn't see Dave's alog abou this exact issue last night .
Dave has restarted the IOC in hopes of recovering the temperature information for us.

If that doesn't continue to work, then I will make an ndscope of the Dust Mon Temps and put that up on the FOM for screenshots instead.
Thanks Dave!
