I am on a vessel anchored in Guanabara Bay near Rio de Janeiro. I observed strange red and white flashing lights high above the corcavado mountain. The brighter lights were 2 red lights which seemed to move closer with white lights randomly flashing in the same area. There are lots of flights in and out of Rio and there are also masts in the area of corcavado. These lights were at a much higher altitude and did not move like a plane would. One of the red lights appeared to move vertically up in a slow manner. Possible some completely normal explanation, but i did find the event curious.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information. PD))
