High speed cloud orb caught over Avare, Brazil

On January 31, 2015, a mysterious spherical-shaped UFO has been sighted and photographed over the city of Avare, in Brazil. This case has reported on MUFON website. Images are really impressive.

Scott C. Waring explains:

This is a great UFO report from Brazil. He describes a fast moving object. Notice the softness of a cloud forming around it. This is a cloud orb, but caught in a sky with few clouds making an easy catch. SCW

Eyewitness states:
In early January 2015 I sent some pictures for you MUFON and that was de Pesquisa them to me. You could not reach an agreement, the objects were undetermined. Well, this object photographed 31/01/2015. You see the photos. Unlike last time, this time I and three more witnesses observed the object move at high altitude and high speed in front of us. The phenomenon moved around for 1 minute and 20 seconds until it disappears. I took some pictures of the object 7 with the zoom lens at maximum position of 300 mm. Only those coconut trees are to give the reference of the object distance to the ground, where it went. Do you think I should send these photos to MUFON? I think the page there very difficult and time consuming to load. I did all the photos in RAW (high resolution). If you can help me thank you.
