April Lyrids Meteor Showers (Peak time and Condition)
April Lyrids reach its maximum at the end of April every year. April Lyrids sometimes shows outbursts such as 1922, 1945 and 1982. Its peak is very narrow and sharp. In Radio Meteor Observations, April Lyrid activity is caught every year. But it is very weak activity level and norrow period. The peak occured at λ⊙=32°.2. This is earier than visual observation peak at λ⊙=32°.32.
