...Forecasters expect the 2009 Perseid meteor shower to peak on August 11th and 12th. Moonlight will interfere with the display, but not ruin it. Sky watchers in dark country locations could see more than 100 meteors per hour, and perhaps as many as 200 if Earth passes through an anticipated filament of comet dust that is crossing Earth's path. NASA's Meteoroid Environment Office warns of a possible outburst at 0800 UT (01 a.m. PDT) on August 12th. [live meteor counts] [possible outburst] [observing tips] [sky map]
