The annual Lyrid meteor shower reaches its peak tonight. Conditions this year should be nearly ideal. The waxing crescent Moon sets around midnight local daylight time, leaving the prime viewing hours before dawn Moon-free. The shower’s radiant — the point in the constellation Lyra the Harp from which the meteors appear to emanate — climbs nearly overhead just before morning twilight starts to break. Under a clear, dark sky, observers can expect to see 15 to 20 meteors per hour.
