I live in central Polish city of Lodz, I work full-time as software developer for an IT company. I make photographs rather irregularly, in moments of leisure and on holidays or when the view outside my window seems worth capturing with my camera. When I find a particular photo interesting enough, I upload it to Weather Underground to share it with you.

Caption: This plane has made at least 4 high-altitude circles (or more precisely ovals) leaving spiral-shaped contrails. Later another plane appeared to follow it making similar maneuvers and after some 10 minutes they both flew out of sight. Looks like something unusual has happened, but I could find no related information on TV or Internet. I have an amateur ADS-B receiver at home (AirNav RadarBox) and I had turned it on to see what plane it was before it flew away, but it looked that plane’s transponder wasn’t functioning.
