Upper Air winds during the day were from the southwest quadrant, opposite to
the movement this object. A check was made with a local astronomer concerning
the possibility that a satelite had been observed, but it was determined that
no known satelite as moving in the direction of this object, nor could the
shape of any known satelite have been noted with the relatively low power scope
on a theodolite So.
The estimated size of the object, the distance away and its estimated speed,
as showm on this questionnaire all based on an alt 30,000 feet3
as I am certain that is minimum altitude the object could have had, as indicated
by its passing above cirrus clouds. If the object was much higher than 30,coo feet,
