Comments: 

00:50-01:10 UTC: Relatively large fluctuations in DES QuickReduce seeing (1.4+-0.3''), while DIMM seeing stable (0.9'). Update 1:30 UTC: Really poor seeing, around 2'' in g, 1.6'' in Y. DIMM says it is around 0.8''. Update 1:50 UTC: now DIMM seeing has gone up as well, it seems to respond a bit slow
