The Perseid meteor shower is a very popular annual event, with Perseid parties being held around the globe each year. Best seen from the northern hemisphere, the meteors will appear to radiate from a point in the constellation Perseus - between the "W" of the constellation Cassiopeia, and the bright star Capella (see image above).

Every year I see posts about this year's shower being the "shower of the century" or it will be the "brightest shower in the recorded human history!" I'm not so sure about that this year... although the Perseids typically puts on a pretty good show at about 100 per hour, the waning gibbous Moon will be bright, and just to the east of the radiant; this will obscure many of the dimmer meteors.
