This sequence of images spans 11 minutes and shows how quickly the moon rises above the greatest distortion near the horizon. The distortion is best seen at full moon - only a day or so either side of full and the changing phase dominates the shape.

To compensate for the change in extinction the exposures were decreased from 0.8 seconds to 0.04 seconds.

The dashed line marks the true horizon, which in this case was very close to the astronomical horizon.

In this sequence of images taken roughly 10 minutes apart the moon quickly becomes less reddened and less flattened as it rises.

The images were taken at altitudes of 0.7, 1.6, 2.1 and 3.0 degrees.
