Although the Lyrids are known for being unpredictable in the number seen in any given hour, many astronomers are predicting about 10 to 20 per hour, but with a peak at upwards to 100 in an hour on April 22nd. However, these meteors can be seen anytime from April 16 to 26, 2013.
The meteors within the Lyrids are material left behind the cometary tail of periodic Comet C/1861 G1 Thatcher when it sheds some of its dust as it regularly visits our inner solar system, and moves around the Sun.
The radiant (origin) for this shower appears within the constellation Lyra, specifically near its brightest star, Alpha Lyraw (Vega). Thus, the meteors are also sometimes called the Alpha Lyrids (or April Lyrids).
The constellation Lyra will be found in the northeastern sky in the late evening on April 22nd.
During this time, the Moon will be in the sky until the early hours of the mornings.
Thus, a good time to see the Lyrid meteor shower is between the time that the Moon sets in the morning and the dawning of the day. The meteors will appear much brighter without the Moon interfering.
However, any time after midnight should produce good viewing of the Lyrid meteor shower in 2013, which have been seen, and recorded, for over 2,600 years.
