Okinawa 7 February 1953

Ie Description of Incident

At 2122 lacal time radar tracked an unidentified object for 15 minutes and
alerted a local interceptor squadron. An F-9k scrambled at 2123 hours, climbed
to 15,000 ft., picked up nothing on airborne radar but at 2145 did make visual
contact with a bright orange colored object which seemed to change to red and
grean at a speoiel intarval. Object was seen by the pilot and the R.C. for
approximately 15 minutes after which it disappeared benind a cloud at an azimuth
of 290°, low on the horizon.

Ii. Disueussion of Inctdent

— ——_———-

The weather consisted of scattered stratus clouds. tio informaticn is avail-
able on almosogheric phenomena such as temperature inversions or moist:re-laden
clouds which could have given a spurious radar return. It was determined at the
base making the report that the F-9) had sighted the planet Venus which is extremely
bright at this time of year and which also is located at a 279° azimuta from Okinawa
10° above the horizon. It is probable that merely by chance ground radar received a
spurious plot on its scope and accordingly vectored the F-9k to a position where
Venus was very ¢pparent. No strict correlation between the electronics sighting
and visual contact cain be made. ‘

IiI. Conclusion

Probably Vanus.
