Duration:10 seconds
What may have been another Corvallis fireball lit the night sky for 10 seconds above the cloud deck at 2254 PDT.

What may have been a repeat of the 2/21/00 Corvallis, OR fireball event occured at 2254 PDT on Monday, April 17. About one-fourth of the night sky was illuminated with a series of rapid, strobe-like pulses of greenish light above the cloud cover. Definitely greenish, not blue-white like lightning or sheet lightning. No thunderclap or any aircraft sounds. The light source moved from south to north along a line paralleling Interstate 5, east of Corvallis. Thick, broken clouds prevented any direct view, but the multiple green flashes were distinctly brighter than the moon which was south and east at the time of the sighting. Estimate base of broken cloud cover at approx. 6,000 feet. Winds W-SW variable at 10-20 mph. This sighting was similar to the February fireball in terms of the definite greenish cast and the fact that it suddenly flashed into view, i.e. the immediate, lightning-bright flash above the cloud layer, and that tonight's whatever it was traveled what seems to have been the same south-to-north trajectory. At least three or four distinct, bright green flashes against a bright green glow that covered at least 25 percent of the sky for about 10 seconds.
