At exactly 5:42 hrs i observed a starlike white light (brighter than any other start) traveling from south to north in a straight line to the west of me at approximately 45 degrees in the sky. the object appeared to be at extremely high altitude and traveled faster than most passenger jets or satellites. as it passed it would occasionally pulsate extremely bright. it then faded down slowly and vanished completely in a completely clear sky just to the north of my location.
