Yellow and greenish fireball streaking to the west over north central OregonOn Thursday morning, 25 July 2013, at approximately 00:26 PDT, I witnessed a fireball travelling west and slightly south from my location on the east side of The Dalles, Oregon.It began in the east-south-east, to the east of the moon, near the lowest star in Pegasus and streaked mainly to the west, disappearing just west of due south. It went under the moon about three quarters of the distance above the horizon as compared to the moon. I could not tell if it was heading due west and just losing altitude, or if it was actually moving somewhat to the south.The streak itself appeared to have a yellow/gold center with trailing "sparks", but the outsides or borders of the streak above and below had a green tint to them. The streak terminated without any discernable report, either visual or aural. It just disappeared at a point estimated at an elevation about one half the distance from the horizon to the moon, but well west of the moon, between Sagittarius and Aquila.The entire streak lasted an estimated 3-4 seconds. The length of the streak was considerable, probably consisting of as much as a quarter or even a third of the total length that it travelled in the sky.My best guess is that this was a meteor, not any type of craft.
