In the night of August 2, 2007, around 1 a.m., two witnesses observe the movement of a green luminous ball. Spinning in a spiral on a descending trajectory, the phenomenon disappears from their view behind a hangar. No noise is heard during the observation of the phenomenon. No other testimony was collected on this phenomenon in the area. The IPN investigation was unsuccessful due to lack of contact with the witness. The characteristics of the observation suggest a meteor (duration = 2 seconds, green ball color) not listed, but any investigation is impossible due to lack of contacts and therefore of information.
