Observation time: 19:17 - 19.21; 2 objects (doublepyramides) coming from south, if they was 8-10 km high, than the moved ca. 800 km/h speed. definitely no airplanes, no sound, no trails, (creepy!) nr. 1 was slowly turning northeast (in direction to göteborg); nr. 2 continued north and disappeared over a cumulus cloud, nr. 3 appeared later from south (19:21), but toward direction unknown, (the observer had to leave the site, and was not able to continue observation, the lokal busdriver can confirm the event.) the shape could be seen as a kind of very big silver hot-air-balloons, but the high above the cumulus clouds, the speed and the changed direktion for nr. 1 to NE makes it unlikely to be balloons. the airspace is crowdy by regular airplanes, but there was no airplanes by the time of the event. the flyingroute was over open water (kattegat) right in the middle between denmark and sweden, and towards norway. there are no pictures from the event. (the foto here is from internet), only to illustrate, what we observed.
