Lyrids 2016: prediction of activity
to the list of predictions

In 2016 the Earth passes relatively close to 1 rev trail of the Lyrid stream. Minimal distance is 0.0017 AU and will be passed be the Earth at 21:44 UT on 21 April. This allows to expect a small and short enhancement of activity with ZHR=3-5 above background action. Brightness of trail meteors is expected to be low. Unfortunately, activity check will troulbled by the full Moon staying above horizon all the night time.
