Engineering night: everything worked well (except the seeing!). Spectrophotometric standard stars in each CCD were taken with filters M411, M464 and N395. In addition a sequence of a globular cluster in N395 was taken to help MAGIC calibration. From 04:00 LCT until the end of the night, KB observed the Fornax field for seach of z-dropouts.
