Sunset Anomaly (Posted on 2016-03-09) Difficulty: 2 of 5
The cover of the June, 1979, issue of Sky and Telescope magazine had a 38-minute time exposure photo showing the setting sun over Boston harbor. It was taken on September 25, 1973, three days after the equinox.

As the sun is then south of the equator, the sun's path in the sky should be an arc of a lesser circle (as opposed to a great circle, which would appear as a straight line on a photograph) centered on the south celestial pole, which is below the horizon, to the left (south). As a result, the concave side of the path should be toward the bottom/left. However the picture shows its concave side is on the top/right, toward the north celestial pole. What happened?

That it was a highly technical explanation behind the bending. Notable!
