Good show, Leo!

On my roof, with clear skies and outside any major city, but in a light-polluted area generally, I saw 40-50 in an hour before the cold drove me back in.

I'd concur with the "short bursts" observation; sometimes I'd go a couple minutes without any, then get three or four within a few seconds.

As you'd expect, distribution across the sky was fairly random, but there seemed to be a couple "hot spots" that got more than average. No doubt this was mere coincidence. However, I did see a few "clusters" where two or three appeared together in the sky within a second of each other. Perhaps these were parts of one grain that divided high in the atmosphere, or small bits brought close together by mutual gravitation; or just coincidence again.

A few were quite bright. But I believe I missed the single best one. As I was dressing to go out, there was a flash like lightning. I wish I'd been outside for that one!
