Coming two nights best for the Perseids, with only modest lunar interference

The zenithal hourly rate was already in the 50s this morning UTC (video data also show a steep rise of activity), and the peak should be reached around noon tomorrow: the nights 11/12 and 12/13 August promise the highest rates, depending on the time zone.
