ON the nights of february 27th and 25th, 1953, I observed
an unidentizied object in the sky at approximataly 2120 hours,
The object appearad to be stationary in the sky ana its’
aporoximats position was northenorth wast. t+ was approximately
1) degpses above tha horizon.
As I continusad to watch the object, it changed colors. (jnen
first observed it was ea bright red. I[t then changed from red to
wnites to yellow to green, It repeated this cnanzging of colors but
ja no particular pattern,
On observing it for about ten minutes it started to receed on
a northenorth west course and appeared to lose altitude,
I watchai it mr about ten minutes sors, after which time it
was lost to sigim over thea horizon,
On the might of Paoruary 28%, its* action wers ths same as
the previous night except in the last ten minutes of its’ occurance
it swerved out of its' course by approximately 15 dsgroes in less
than 5 seconds. It swerved onto its original course withe ‘he same
speed and disappeared over the horizon.

Dover Air Force Base, Delaware 26 February 1953
Le Description of Incident
At 2130 EST a dull red colored ight was observed low on the western horizon
by several military personnel. The light was slowly moving from west to northwest
alternating color from yellow, green, red, and back to white. After being observed
for spproxinately five minutes, object disappeared below the horizon.
Il. Discussion of incident
Observers were, in the opinion of the preparing officer, reliable. Ab the
time of sighting, weather was clear, visibility eight miles. F-9's in area on
other missions noticed nothing unusual. Due to the fact that the light was seen
soving from west to northwest low on the horizon and then to disappear over ths
horizon and that the planet Venus can bo seen in that direction vory plainly during
this part of the year, it is quite certain that the licht observed was Venus.
ATIC'’s contract astronomer was consulted and he concluded that the object observed
was definitely varus,
Ill. Conclusion
Astronomical ~ ‘snus,

I. Description of Incident
At 2121 EST four AF personnel observed a single light of alternating colors
with red predominant. The light was due west of Dover Air Forces Base and about
20° above the horizon pursuing a very gradual course from west to northwest.

over the horizon, There was no air traffic in the area,
IL, DPiscussion of Incident
As in the case of the Dover sighting of 25 Feb 5%, it was the opinion of
ATIAE=—5 that Venus caused this sighting. ATIC's contract astronomer was contacted
and definitely concluded that it was Venus,
Ili. Conclusion
Was Venus,
