2012-02-23 - Scapoose, OR - Light

While on a drive out in the farm land of Scapoose around 2 pm today Feb. 23 2012 my boy friend and I witnessed a large cluster of glowing almost glittering white orbs of light floating and swirling around in the sky. They would appear dark and then get increasingly brighter. We watched for about 1 minute and a half and then watched some break of and form another cluster lower than the first and then some more break off and form another cluster higher up. They just swirled around in a spiral motion and then recollected and flew off into the sky getting brighter once more and then disappearing. My boyfriend and I really want to know if any one else in the area saw this or if anyone may know what it could have been. I know it wasn't a flock of birds or anything like that, it's nothing I have ever seen before I hope this explanation is clear enough. Thank you!
