During the dark hours before dawn on Sept. 9, 2008, a surprising flurry of meteors had showered the skies above Huntsville, Alabama. More than two dozen of them were fireballs brighter than Jupiter or Venus; a few even cast shadows.

An unexpected flock of fireballs burst over the eastern United States early Sept. 9, but sharp-eyed Marshall Center astronomers were on the case. Lasting almost four hours, the shower contained about 25 meteors that were as bright as Jupiter and Venus in the morning sky. Early analysis suggests that NASA's photos are the first-ever observed outburst of the September Perseids, which result from an unknown comet.
25 bright fireballs were recorded over the eastern United States.
"Our SENTINEL all-sky camera picked up 25 bright meteors in a shower that began at 06:20 UT and lasted approximately 4 hours. Most appear to have a radiant near Perseus, leading us to hypothesise an outburst of the September Perseids" - Bill Cooke, Marshall Space Flight Centre, Huntsville, Alabama.
