I saw through a 5" telescope a black tear shaped object against the moon,s disc. It moved spinning its backwards directed narrow end.Just the day after lunar eclipse of december 1999. Weather clear. I was adjusting a portable telescope(some 5"diam.)on the terrace of my 3rd floor apartment, and focused it to the moon, that was rising to approximetely 30 deg. As soon as I located the left inferior arc of the satellite, my attention was attracted to a black, tiny pear or tear shaped object that moved in "front" of it with a peculiar balancing spinning straight displacement that mantained the narrow end backwards. This lasted a blur. Assuming the image was inverted, the actual direction would be an ascending 45 deg. right to left as seen against the brightness of the moon. I was motivated to submitt this observation after reading the report cited from NUFORC by George A. Filer in Filer,s Files #31,8-8-00, that occured in Bronx, N.Y.((NUFORC Note: Individual who submitted report has professional credentials, and is an experienced amateur astronomer. PD))
