If astronomers' predictions hold true, the Gamma Delphinids may undergo a rare outburst that could even equal the famed August Perseids—with rates of meteors reaching as high as one or two shooting stars per minute.
The Gamma Dephinids were first discovered on the evening of June 10, 1930, when two astronomers from Baltimore, Maryland, noticed that despite the glare of a full moon, a fast and furious flurry of shooting stars was radiating out from a previously unrecorded spot in the sky. Most of the meteors were reported to be as bright as the brightest stars in the sky, making them quite spectacular. (Related: "Perseid Pictures: Meteor Shower Dazzles Every August.")
"Starting at 9:15 p.m. EST, they started seeing meteors pouring out of the small constellation Delphinus (the dolphin). The meteors had short trails and brief duration and were yellowish white," says Peter Jenniskens, co-author of a 2003 study that predicted a new outburst might take place this year.
