Comments:

Mid-night switch to SOFI to accommodate observations needed for DDT proposal, then back to EFOSC to catch the GW counterpart candidate!

00:49 UT - Issues with rotator after SOFI image analysis.

02:09 UT - SOFI rotator broke again. OB aborted (lost some K-band images), moved back to EFOSC

If possible, will finish observing other SOFI targets tomorrow night.

In other news...the soft jazz music persists. Has reached the stage where observers can still hear it even when it's not playing.
