This night (November 16/17) at 01h57m UT our videocameras have recorded a very big flash near the border of the observed field, in the North-East quadrant of the sky. The fireball, which we estimate in the video about -18m, was visible certainly from Slovenia and Austria too. Enrico Stomeo Italy, +45.5682 -12.1149 +20 (IMO code 14083)
