Migration tonight

It looks like migration could be pretty strong tonight, check out the radar image below.

*update* I went out and did some moon-watching thanks to the post that Woodcreeper put on the Jersey listserv concluding the same thing I did; there was substantial migration going on. I counted 60 birds crossing the moon in 16 minutes which is the highest traffic rate I have seen in the few times I have moon-watched.

If anyone knows how to extrapolate the number of migrants passing over from moon-watching results please let me know.
