I. Description of Incident

An observer in London observed a watermelon-shaped object of white light
estinated to be as high as 1,000 fest then disappearing tehind some buildings.
Object was slow moving and was sighted at 0300 for 3 mimtes.

II. Discussion of Incident

This report is very brief. Nothing is known about the reliability of the
obsarver, local air traffic, beacons on water towers, ets. Therefore, no real
evaluation can be attempted although the description sounds like the landing
light on an incoming plane. ;

III. Conclusion

Insufficient information.
