METEOR SHOWERS - these are leisurely, wide angle events that don't require a telescope to view.

Among the best are the PERSEIDS that peak Aug.11-13, and the LEONIDS that peak Nov 16-18.

Both have HOURLY RATES of under 100, with very occasional peaks.  Best seen AFTER MIDNIGHT after the moon has set.

Have you seen a FIREBALL?  Report it at: http://www.cloudbait.com/science/fireballs.html  (and a good place to see reports about recent meteor showers too).
