CAMERA_SERVO has been stalled since 9:56 UTC and is what is stopping us from gettign to Observing.
I tried manually moving the CAMERA_SERVO Guadian up to the next step but it was not moving up in states.
I Really wanted to just click down and rerequest the proper state, but I was unsure if it would cause a lockloss or not then force me to wait another hour to get back up to NLN again.
Contacted Keita at 10:30 UTC to see if he can help me understand more about what was going on, and determine if I can just click down and then CAMER_SERVO_ON again.
Keita pointed out the ASC Dither OverView screen which has the Camera scopes (Screenshots), and then it was obvious that the cameras were not working properly.
We then stepped through the CAMERA_SERVO Guardian code line by line to determine if we can take the CAMERA_SERVO Guardian Down without a lockloss.
Turns out the right thing to do was take CAMERA_SERVO Guardian to down then back up to CAMERA_SERVO_ON. We were successfully able to get to CAMERA_SERVO_ON NLN and get to OBSERING.
12:07 Lockloss possibly due to earthquake: https://ldas-jobs.ligo-wa.caltech.edu/~lockloss/index.cgi?event=1369829200
