With the Moon at waning crescent phase on August 11, observing conditions for the 2004 Perseids meteor activity should be excellent everywhere. Because the radiant is at a high northern declination (+58°), most northern hemisphere observers may expect to see meteors throughout the night. Observers will not want to be north of 60° latitude or so because of the "midnight Sun" in summer. Nor will they want to be below about latitude -32° because the radiant will never rise above their horizon.This site has a star chart showing the radiant trajectory (the strike line from which the shooting stars seem to emanate).
