SIGHTING: SÃO PAULO, SÃO PAULO (BRAZIL)

Witness Testimony

"I was returnig to my home by car.My position was very close to São Paulo (Brazil) downtown.A glitering object calls my atention in the sky ( about 45º zenith angle)In my perception the objetct was very high ( about 6000 feet or more)What was very strange in these spot was the trajetory and the intensity of light:1-The spot crosses the sky in a not linear trajetory ( going from right to left ) going up and down, stopping some times.I use some tall TV antenas to get a good geometrical reference to be sure about the trajetory.Note: my car was not moving because of intense car traffic that allow me to look to the sky during about 3 minutes.2- The object shows a white light with an intensity oscilation ( it looks like a glitering). The light oscilation did not obey a frequency that could be similar to a normal airplane. Sometimes there was no light but only a grey spot for 2 or 3 secounds( I am not sure about the shape of the object because it was too high).But the light, in its maximum intensity, was very strongAs the traffic allows me to move about 300 feet ahead, I park my car to get out and watch the fenomena better. This takes about 20 secounds, and when I look again to the sky where the objetc was moving, it was gone. Note: I am mechanical engineer and have a good logical perception of phisical fenomenas."
