It is a pity that over the past week or so we have not been very lucky with the weather. Even though the sky was generally clear, most nights were blighted with the passage of high clouds. The current scanner software can filter out and distinguish proper dark cloud cover…but it is quite difficult to distinguish the passage of high clouds from the passage of bird silhouttes.

And the consequence is a lot of false positive readings ….

Now if only that was migration!! Having actually reviewed some of the trajectories it was surprising to actually find a couple of real sightings!

I guess its time to use the next moon break to roll up those sleeves and put some fixes to that software!
