Late April Meteors

April 22 marked the peak of the Lyrid meteor shower. The Lyrids are considered a major shower though, in reality, they are the weakest of the major showers. You might even be able to call them the strongest minor shower.

The Lyrids were produced by comet C/1861 G1 (Thatcher), a comet seen only in 1861. It is a high inclination (~80º) long-period comet with a period of ~400 years. The shower is also prone to outbursts though none was predicted for or reported this year. On the April 22 UT, a total of 21 Lyrids were observed. The star chart below shows the radiant of the Lyrids halfway between Lyra and the keystone of Hercules.
