We actually had a period of time this morning with no clouds and seeing under 3 arc seconds, with an average of 1.9 and a standard deviation of 0.7
It was interesting that initially the seeing was not particularly good and then suddenly improved and stayed that way consistently for over an hour.
Not sub arc second that some folk talk about but better than we've had for over 3 months
