April 11 – 20 Meteors

The period of April 11-20 sees a little more diversity as a number of showers become active. Though most are minor, the Lyrids (LYR) are the first major shower since the Quadrantids of early January. Unfortunately, the Lyrids introduce a theme that will be all too common this year, a major shower ruined by bright moonlight.
