The Perseid meteor shower will reach its maximum rate of activity. Some meteors will be visible each night from 23 Jul to 20 Aug, but the best show will be on this evening. The maximum number of meteors expected to be visible from a dark location is around 80 per hour (ZHR). The Moon will be 7 days old at the time of peak activity, and so will present significant interference in the early evening sky. Shucks again!
