i was observing the sky with my sister and my father on the roof of my grandmother's house in Vargem Grande, and we saw a red-orange light in the sky. We thought was common paper balloon , my sister placed the camera on a small wall, took pictures and a strange shape appeared in the screen. The object was slightly bigger than a star and it was slowly ascending. We felt excited about it, we thought we caught a picture of a UFO. I can't remember when it disappeared, and why we stopped to take pictures... Earlier on that day i was going to the house by car and i saw for 2 seconds an "different" object in the sky moving foward with a cloud of smoke behind it. Trees entered in my sight and for 5 seconds i couldn't saw the object, and the when i could saw the sky again, the object and the smoke was gone. i thougt this 2 facts are related... It's common to see paper ballons in the area. There's a story about an abduction in a lake near and my grandfather told me stories about a fireball over the near mountains long time ago. and sorry for my english
