Triangle-shaped object and a bright pulsing lightMy name is Philip Butkiewicz and I live in Szczecinek since I was born... On the night of this event I was walking back from my girlfriend's place and sighted a triangle-shaped object, lit with multiple white lights along its edges flying over from city stadium, continuing over Primary School #1 and disappearing over the chimneys of Kronospan factory. I immediately called my girlfriend to confirm I'm not going nuts, turns out she was seeing the same thing from over 700 meters away. After the object was gone I continued on my journey back home, only to notice a strange north star-like object that appeared to be blinking on and off. I watched for 10 minutes then went back home. A day later, I was on my way to do some shopping when I noticed the same object in the sky, but now it was in different position - it was on south east and was much brighter.
