08:09 - Q1623_Uspec_2

08:17 - First blue image delayed due to another fiber link that happened just before the end of the exposure and that was recovered automatically. Almost 5 min delay.

08:22 - Happened again at the end of the exposure. this time the system did not recover. Power cycle again, then cut exposures in 2x150s.

08:31 - restarted the camera. dofpia again

08:36 - Q1623_Uspec_2 again

• Uspec 2x150s instead of 1x300s
• Seeing around 1.4". Useless, stop the OB and go to Rigliaco field_1

08:56 - Exposure - Rigliaco_Serpens_UsR_1

too few downloaded pixels on the first blue and red images. Blue controller and/or fpga are definitely having problems tonight, but the red problem is quite new.... also a too many downloaded pixels from the blue

09:28 - dofpia

09:31 - Exposure - Rigliaco_Serpens_UsI_1

09:36 - Blue ccd controller error again . Power off/on again

09:41 - No way. Blue FPGA won't load. Power cycle again

Meanwhile error message lbckill/lbcstart like

09:48 - Restarted

09:52 - No way, ccd controller error again.

09:56 - Talked with Fernando, may be a fan is not working. Power off and let it cool for ~15 minutes. Then try restarting again.

10:03 - Turn OFF hanged so lbckill/lbcstart but this restarted the camera, FPGA not loaded. Power OFF then wait 15 minutes, night is practically finished.

10:18 - Power ON camera.....ok!

10:23 - Try dofpia again

10:39 - After 8 images out of 32 CCD controller error again. Turn off and let it off until flat fields.
