Airplane transiting sunspot AR2470 on December 20, 2015

Just as I was imaging sunspot AR2470, an airplane transited the spot. The original acquisition was done at 70fps, but this video was processed at 20fps. The scope used was an 8inch F/5 Newtonian working at F/20, and ASI120MM-S camera. A Baader solar filter was used in front of the scope.
