Whats the eta on the peak of the persiedes northern hemisphere 12aug09?

The predicted peak is at 18h UT on August 12, which is in daylight for all of North America. But I wouldn't worry about it, since the Perseids have a broad peak. The best time is probably after midnight on August 11/12, followed by after midnight August 12/13. Unfortunately, there will be a bright Moon interfering both nights.
