I've seen a lot of movements in the sky lately. In Aalborg, Denmark.This one was the most affective. The most memorable out of all the sightings I've experienced.That is why this is my very first report also. Previously I've just seen flying orbs and huge stationary flashes in the sky. Like signaling that they are out there.1) I was sitting in front of my apartment building waiting for some UFO sighting or movement.2) It moved with constant speed and then went slowly really, really bright.3) I knew instantly that this must be UFO (I've been waiting for this kind of sighting)4) It's size was at first like normal (like average star) and its brightness the same. It moved with constant speed and during its flight it started to get bigger and brighter. Its brightness can be compared to full moon in a clear night sky. It was white. Then it went slowly back to its previous size. It didn't change or lose its direction or path.5) I was by myself "WOW", "cool" and literally giggling. Totally amazed because this was what I've wanted to witness for a long, long time.6) It appeared out of nowhere. Had its flight. Went back to its previous size and disappeared.
