This is not the supermoon! It is the day after but still very impressive. The building looks like a rocket ready for liftoff and one of the astronauts can be seen in the window, probably smoking a cigarett. This picture was taken at 18h 58m 28s UT and the moon was in fact bellow the horizon at - 0°22' and would not be visible if it were not for the atmospheric refraction, bending the rays of light and "lifting" the moon above the horizon. The building is 86 meters high and 5 km (3.1 miles) away. The second picture is a sort of timelapse-compositon of 4 frames added together in Photoshop. Another effect of the refraction is the flattening of the moon (or the sun) that is extreme close to the horizon but diminishes quickly when it gets higher. The 3rd picture is a gif-animation of 3 frames Frame 1: 19h 01m 15s UT, Altitude: -0° 04' Frame 2: 19h 04m 21s UT, Altitude: +0° 17' Frame 3: 19h 29m 25s UT, Altitude: +2° 58' The time difference between the first 2 frames is only 4 minutes and another 25 minutes between frames 2 and 3.
