6. The sighting which occurred in Colorado on 29 Septamber 1960 gives
all indication of being due to atmospheric refraction. ATIC has taken
action to obtain weather data afor the area on the date of the
slghting  A complete analysia will be accomplisned when ATIC receives
this aduitional data.

SUBJECT: Transmittal of Weather Records 25 Oct 1960
TO: A ATIC/WPAFB
We are inclosing with this letter photographic copies of the WBAN
Form 3l (Adiabatic Chart) to include the period 26 s September through
30 September from Albuquerque, New Mexico, and Grand Junction, Colo-
rado. This transmittal is telephone request of
20 October 1960.

Junction Colorado
New Mexico. In addition, many people in the genera eported
seeing unider ified flying objects.
2. The object viewed from Grandi Junction was described as a round,
flashing red, green and white light and reported as sta-
tionary. The object was in sight for Lo minutes.
3. The witnesses at Grand Junction and Farmington used a thealolite
to measure the angle of elevation of the object and then by
lation arrived at an altitude of 373 miles for the ooject.
4. ATIC obtained weather data for the date of the sighting from Air
Weather Service, Asheville, North Carolina. The adiabatic charts
for the area show an inversion at 04C5 on the date of the sighting.
The ArIC ccnclusicn is that effects produced by this inversion were
UFO sis 9 area.
5. The statior maasire
objeat, if were the sase one, would have been further from one
station than the other, thus a geometric inconsistency. If the
objects viewed wero due to the inversion, then the apparent angles
would have been appro
6. In the instances of
and increasing rather rayidly as altitude i increaseslight rays
which 1 pass through this layer are bent toward i the earth and effec-
tively the distance to the horixon is increased from any given point.
Mirages which result from these condiitions are sometimes referred to
a3 "locming nirages" because unsteady conditions may cause a distant
object to suddenly LoOm' above the horizon.
7. From imited impossible for
ATIC to dete what speci bject was viewed by each witness;

however, it is concluded that the inversion was responsible for
comnon objects being misidentified and mistakes
actual locatian.
