Comments:
01:15: We start the night with a problem in the mirror (something with the detectors). Because of this, image analysis was not possible. The problem was not solved but we could start the observations.
05:49: The problems with the actorsA (in the mirror) continue. We changed to EFOSC and spent some time trying to solve the problem (doing some focus).

Aborted. Nothing visible in the acquisition image. The problems with the mirror continued. We did some Focus and jumped to the next object. The quality here was bad. |
