Fast wind after lunch was caused by some cumulus clouds not fare away. This clouds went away just before midnight as predicted by Aladin. Cool... I started my run on 3C 454.3 in R and V bands. Since some clouds were all across the sky, certain exposures are affected (visualy confirmed during run) and will contain much more noise . Non stable conditions are also visible on PV measurement.


Just before dawn I moved the telescope to IC 59 and get a few one minute exposures. Batch exposures are still buggy as they omit to save files randomly. Which is quite annoying :)
