The annual Lyrids meteor shower peaks during the night of April 21st/22nd and this year's event promises to be a good one, as the 23% illuminated waning crescent Moon in Aquarius, won't significantly interfere. Normally, you can expect to see up to 20 meteors per hour under ideal conditions. In addition, the Lyrids do occasionally produce brilliant fireballs, that streak through the sky and cast shadows as they disintegrate in the Earth's atmosphere.

Unlike sporadic meteors that originate from anywhere in the sky, periodic meteors can always be traced back to the same part of the sky (radiant point). Therefore, spotting this type of shooting star should be easy, just focus on the radiant point. Correct, not quite. The problem is that, although the meteors do originate from the radiant, they almost always streak across the sky many degrees from it. Therefore, good advice is to lie down on something like a reclining chair, look skywards and scan a large area of sky around the radiant, but not directly at it.

The Lyrids radiant is located inside Hercules. It's positioned close to the border with Lyra and only 6 degrees from Vega (mag. 0.0), the 5th brightest star in the sky. The best time to observe is around midnight and during the early hours of the morning.
