The annual Lyrid Meteor Shower is expected to reach its worldwide peak on 2011 APR 22 at 19 hr UT. The shower actually runs from about APR 16 through APR 26. For any particular locality observation is generally best between local midnight and dawn. A full and then waning gibbous Moon may provide a bit of a hindrance.

For a single observer the Lyrids produce roughly ten meteors per hour with a typical magnitude of +2, which is similar to the North Star (Polaris). However “Lyrid Fireballs” get bright enough to cause shadows and leave smoky trails. And occasionally as in 1982 up to 90 meteors are seen per hour.

The Lyrids are particles from Comet Thatcher and have a radiant in the constellation Lyra. The radiant is the point toward which the meteors’ tails point, but they can be seen anywhere in the sky.

I’ve drawn a table of the major annual meteor showers for this decade. It includes Moon illumination data. It can be seen at http://www.CurtRenz.com/asteroids

Photos and reports of the meteor shower would be welcome additions to this thread.
