Nice bright fireball with impressive tail declination 10 to 20 degrees disappearing over Utanum ridge or thereby....maybe e 20 miles away ... I was on I 90 just beyond mile post 106 headed SE....I drive I 90 from Seattle to Yakima every week night....in my 18 years have seen many meteorites...but nothing like this.Last fireball I saw was in Seattle about 1986 ...
