First half of the night shift (21:00-03:00; Stefano and Juan): fog, snow and wind. The telescope is parked. The de-icing is on. At roughly midnight (CET) the wind calms down and it is not snowing anymore. It seems that the fog might also disappear soon. At 00:22 CET the sky is clear and the telescope moves out of the parking position. We now need to wait a bit until the primary surface relaxes after the de-icing. Frederic goes up on the platform to remove some snow and ice from the subreflector. After the usual pointing/focus, we switch to 010-21 and we observe NN repetitions of NGC1333-C2, thus reaching MM hours in total on this source. Tau(225)~0.20-0.30. |
