Small, white, lumenescent sphere observed drifting through chemtrail activity from High Desert, Central Oregon.

small (estimating the altitude @ a few thousand feet HIGHER than normal chem-trail activity and this sphere was presenting aproximately 1-2cm diameter), white on a blue field sky - hazy orangish lumenescence when it played through a fair sized and expanding chem-trail emission; feathery dot. Noticed as I sat on the deck this day, it traversed a path E-S maybe 2-3 miles (slow easy lazy hover with steady drift).  Pointed this out to 2 other adults to make sure it wasn't just my eyes. Both confirmed the presence and neither had an explanation.  This is the 2nd time this month I have observed this craft.  Other time was on a late afternoon early in September or late August.
