At the sighting there were 5 people, it happened around 0:00 CET, we thought it was sattelite, but then we noticed it was changing course - just a little to the left and to the right and once it nearly stopped. It wasn't flying as our planes would, but more of something of what you would see on a computer - the little turns to the right and left were not natural. It flew from the direction of Logatec or Vrhnika and continued to Grosuplje, almost right over us. The sky was misty, but the light from it was able to penetrate the scarce clouds, it also looked like the light was the reflection of the sun, so it must have been high up and was not too fast. Actually a plane came 15 min later and it was going faster, but it was probably flying not nearly as high
