In investigating FC2 temperature trends to try and optimize SQZ, I ran into an oddity with FC2 OSEMs that was also seen by the FCES VEA Temps. Running through potential causes with TJ, we ruled that this was not a cause of H1 being unlocked since the other times H1 is unlocked don't have nearly as much noise in FC2.
There was a 7.6 EQ at this time, which explains the FC shaking and the lockloss. Why would the Temp_DEGF plots see a change too? Screenshot attached - the EQ arrives at T2 but it seems like the ripples in space temp are seen in T1.
