Orange ball of flame crosses North Sacramento - no news reports11/11/2012 approx. 1757 hrs.Driving north on Morse Ave. from El Camino in North Sacramento, observed large bright yellow orange light traveling from NNW. I stopped my vehicle to get better view through tree branches. The object moved at a deliberate pace along a flight path nearly due south. As it passed overhead, it appeared to be a slowly roiling ball of orange flame, however showed no disturbance from surrounding air, no streaking, no trail, and no discernible noise.I tried to observe signs of craft disintegration due to inflight emergency, but no debris or disturbance of flight path was visible. Duration of the observation was no more than 3 minutes from the appearance at 40 degrees above the N horizon to 30 degrees above S horizon when the object flashed off and on 2-3 times before disappearing from view. As remarkable as this sight was, the relatively undramatic speed and straight path made the appearance seem relatively mundane.I was raised in the approach path of a civil airport and have lived for 18 yrs. within ½ mile of the local airbase , and am quite familiar with the appearance of all manner of civilian, commercial and military craft in nearly all conditions; this one, despite the lackadaisical pace, was unique in my experience.
