WOBBLE

I have been long fascinated by the analemma effect which affects the location of the sun on rising and setting.

It accounts for the sudden changes in rise and set time as well. Uneven incremental changes.

Movie: Analemma Over New Jersey

I had seen photos of this phenomenon before but never a time lapse movie.

Watch the seasonal change on the ground.
