- These are clear proofs that, at least this evening, the Sun is setting further North. There is no doubt about it!
This webcam on the Aeolian Islands looks out over a lava flow dropping into the water, out over the crater area noted, pointing at a 45° angle NW to the webcam. Note the ridges to the right and left, on the topo map, of the webcam, showing the angle.
Per Skymap, for this date and time of day, at 5:11 PM on July 18, the Sun should be sighted almost due West, at 275°. However, the actual angle shown is an Azi of 315°, a full 45° too far to the North at sunset!
