Tonight might just be the night to be out late looking skyward, as what is called a long duration meteor shower, lasting no longer than 30 minutes might occur.  Scientists aren't quite certain, and the only way to know for sure is to go outside in the wee hours and look up.

It's the possible repeat of the Gamma Delphinid Outburst.

This is the story:

On the evening of June 11, 1930, three members of the American Meteor Society (AMS) reported that they observed a flurry of meteor activity occurring between the hours of 2215 and 2245 (1015-1045pm EST) from Maryland, USA. These meteors were seen despite the fact that a nearly full moon was present in the sky during the entire display. No other reports of this activity was reported, leading to some doubts of the authenticity of this outburst. Of course one would not expect many meteor observers to be out observing under such unfavorable lunar conditions. In subsequent years this radiant was monitored but no further activity was seen on or near this date.

Peter Jenniskens, in his study of outbursts from long-period comets, has proposed that the 1930 event was real and may be repeated on Tuesday morning June 11, 2013. The expected time of maximum activity would be near 0828 Universal Time. This time corresponds to 4:28am EDT, 3:28am CDT, 2:28am MDT, and 1:28am PDT. This timing is favorable for all the Americas, extending west to the Hawaiian Islands. The radiant was reported to lie near the notable double star gamma Delphini, which lies near celestial coordinates 312 (20:48) +17. For observers in mid-northern latitudes this radiant rises in the eastern sky shortly after the end of dusk and is best placed high in the southern sky between 0400 and 0500 local daylight time.
