Hedwig occultation__ 20170228

Discussion:

The circle above is plotted at the expected diameter of Hedwig. The event was clearly well north of the predicted path, and the miss shows that Bill was south of the centre line. The circle has been plotted accordingly.

Missed

Comments: A brief event could have been obscured by noise, the image was a little faint in my 20cm C8.  
There is a possible one-frame drop close to the predicted' time of the event but there are one or two other similar drops at other times.
Certainly nothing to claim without other confirming observations. Report prepopulated by IOTA Reporting Add-in for OW ver.1.8
