OK, let the speculation begin. [View all]
On the night of July 23 and the morning of July 24, a revolving UFO was spotted above Embu São Paulo, Brazil, according to footage posted on YouTube.
According to Projeto Quartzo Azul, a Brazilian UFO website, there were multiple witnesses on the scenesome took photos and others shot videos. The YouTube video includes footage from four different witnesses.
The object has a blue light at its center, surrounded by a circle of flashing white lights with smaller faint red ones between them.
It spins in a clockwise direction and appears to shoot out fire around one minute into the video. When filmed from the side on, the UFO has a blue glow.
It appears at times as the center orb becomes larger causing the southernmost bottom orb become brighter as each one passes in orbit.
Then there's this one which occurred in 1997 over Phoenix AZ. At about 1:12 into the video it appears you can see the objects rapidly speeding into alignment, although this may be due from camera shake, but the corresponding vocal audio suggests the listeners saw it that way as well. Both of these cases as far as I could tell are still unresolved.
