Support - Sheila, Dave, Jonathan  

Problem #1 - Started getting OMC DCPD saturations (due to Violin Modes 508.2 ring up), but lost lock before damping. Contacted Sheila. 

 Problem #2 – Could not give Sheila remote access due to an issue with the authentication server. Contacted Jonathan who corrected the problem (FRS 7677 aLOG #43993). 

 Problem #3 – There was a problem with the Foton filter files generated after last Tuesday’s maintenance window until today at 13:00, when Jim B. fixed it. See aLOG #43992 for description. Contacted Dave B. who rebuilt the Foton files for the SUSs and H1OMCPI. When I reloaded, the filter files the WDs for ITMX & ETMY tripped. By the time this was all squared away the violin modes had calmed down a bit. 

 Relocked the IFO without the ALS_DIFF problem TJ had during the day shift. I had to dress up BS Yaw a little bit, but no other tweaks were required to reach NLN. 

 Back to Observing and fighting with PI Mode-27.
