14:00-16:00: During the maintenance Dave and Samuel used the platform to access the external calibrator in the secondary mirror (ExtCal in M2) to check its connector. It was not fully plugged in! See picture below. It was very difficult to plug it all the way through, we don't why there was so much resistance, but eventually after shuffling a bit the back ring it went through. Now we have again a response on the ExtCal GUI, for the first time since the COSMOCal test in October. The problem occurred probably during the Holography campaign in November. We leave the ExtCal ON, with SetHeaterPower at 100. So in principle the data files should have now the ExtCal signal in addition to the sky signal, both in separate tables, and ExtCal signal not affecting sky signal. To be checked and discuss at the NIKA2 meeting tomorrow.<<BR>> [[attachment:ExtCalconnector.jpg|{{attachment:ExtCalconnector.jpg|ExCal|height=300}}|target="_blank"]] 16:00-22:00: Stergios: Starting with POL mode and DAQ at ~15:00 UTC with 11/5/40 bad pixels.
