Huge cilynder on Hills over Belo Horizonte City-Minas Gerais State- Brasil

I was backing from university at night, walking in the middle of the streert, when, suddenly, appears in front of me , about 1.0 mile away , over the hills at the end of the street a very large flying object,moving not in a high speed. In front of it appears  also a lot of small lights( more than 15), surrounding it  in a perfect circle in front, and  spreading lights as they move. The clarity of the lights revealed the shape of the object: A huge cilynder, with a fixed reator ( it seams to be) and jet of fire spilled from it.The scene delays something between 8 to 10 secs, was very bright and clarify all over the hills . It takes the south direction passing by Nova Lima, Barbacena Cities. Two days after I red the notice on a  local news paper , sayng that at least two observers related itin Belo Horizonte City and also  did some observers from the the two cities  reported
Witness indicates that the date of the sighting is approximate.  PD
