Large meteor streaks across Northwest skies

Large meteor streaks across Northwest skies

A number of people reported a bright green streak lasting for several seconds across the night sky in the northwest at around 9:30 p.m. on Saturday. By some accounts, the bright green streak in the night sky lasted for at least 5 seconds, which is a long time for a typical meteor. People from Salem, Oregon to British Columbia and from Tri Cities to Astoria reported seeing it.

Some scientists estimated that the bright streak was produced by a large meteor burning up in outer atmosphere. It is worth-mentioning to note here two annual meteor showers that are going on right now -- the Delta Aquarids and the popular Perseid meteor showers.

The Delta Aquarids meteor shower is on the peak now, with nearly twenty meteors per hour. The Perseids is expected to peak on August 11-12, but people may see meteors from this shower many weeks before and after the peak.

Meteors are pieces of comet debris that heat up and then burn as they enter Earth’s atmosphere, producing a bright burst of light that streaks across the night sky.
