Comment: 
Another very good night. It could be photometric. The average seeing might be slightly worse than last night, however it was still 1.0"+-0.2". Actually most of time the seeing was at < 1.0". The best FWHM measured on the images was ~0.75" at the very end of the night, which was not seen last night. Had there been no problem with the telescope mirror pressure support, it would be a perfect night.
