The International Space Station (ISS) streaks across the sky over eastern Pennsylvania on February 13th, 2012 at 7:13PM eastern time. The space station’s path across the sky started in the lower left portion of the sky (23° above WSW). It passed between Jupiter and Venus (the brightest two objects in the sky, Venus being closer to the horizon), made an X with some airline traffic, then faded away in the upper right (58° above NNW). It was visible for approximately two minutes.
The final frame is all thirty nine 30 second exposures merged into one image.
