rectangle object with plus and minus symbols was not seen until pix was enlarged.WE WERE WATCHING AN ANNUAL HOT-AIR BALLOON EVENT ON SATURDAY MORNING. THERE WERE HUNDREDS OF PEOPLE OBSERVING AS THE BALLOONS ENDED THEIR FLIGHTS AND WERE LANDING IN VARIOUS PLACES AROUND THE NEIGHBORHOOD. I TOOK PICTURES OF AN EAGLE BALLOON. AT THE TIME WE DIDN'T NOTICE ANYTHING UNSUAL (APPARENTLY NO-ONE ELSE DID, EITHER). AT A LATER DATE AS I WAS DOWNLOADING PICTURES FROM THE SONY HANDHELD CAMCORDER ONTO MY LAPTOP, WE NOTICED A SMALL DARK RECTANGULAR OBJECT UP AND TO THE RIGHT OF THE EAGLE-HOT-AIR-BALLOON. CURIOUS, WE ENLARGED IT REPEATEDLY. WE SEE A DARKER BAND THROUGH THE CENTER BUT ARE MOST INTERESTED IN THE PLUS'S AND MINUS'S AROUND THE PERIMETER OF THE OBJECT. THEY ARE MOST VISIBLE WHEN WE CHANGE THE ANGLE OF THE COMPUTER SCREEN. WE HAVE TRIED TO GET THE SAME RESULT WITH OTHER PIX, BUT CAN'T.((NUFORC Note: Witness provides e-address only. PD))
