Circular, bright object appeared in the south sky; every 20 or 30 mins it would move further north, before finally disappearing about 20:50pm.There seemed to be increased helicopter and airplane activity; one airplane looked like it flew pretty close to the object, before the plane's lights turned off and the object moved its position slightly before continuing to hover.Zooming in with a camera showed a ball of white light that was glowing, but that showed multicolor flickers, like when you put television on the wrong channel and see snow, except this snow was all the colors of the rainbow, flickering and mixing on a greyish white background.((NUFORC Note: We suspect a possible sighting of Venus.
