METEOR ALERT:

Sky watchers in North America might see an outburst of meteors during the early hours of June 11th when Earth passes through a stream of cometary debris last seen in 1930. Forecasters Peter Jenniskens (SETI Institute) and Esko Lyytinen (Helsinki, Finland) predict the return of the gamma Delphinid meteor shower this Tuesday morning around 08:30 UT (04:30 am EDT). The shower is expected to last no more than about 30 minutes with an unknown number of bright, fast meteors. Bill Cooke of NASA's Meteoroid Environment Office will chat about the shower starting tonight at 11 PM EDT. [Meteor radar] SWx alerts: text, voice.
