Amateur astronomer Felix Schöfbänker from Austria captured images of a mysterious Pentagon satellite, USA 290, using a 14-inch Dobsonian telescope. Unlike known KH-11 satellites, USA 290 features a unique five-meter panel and non-Sun-synchronous orbit. Schöfbänker speculates the panel might be a solar panel but doubts it due to its fixed position. Despite capturing potentially classified material, Schöfbänker remains unconcerned about repercussions.
