February the 8th, it just can't fail...

Every year at the same date, the Sun sets right behind the domes of the Tololo Observatory, as seen from our own observing room. However from year to year we can notice a slight shift southward, due to the fact that one year is not exactly equal to 365 days : indeed this is a nice way to "visualize" this well known effect.
And we try every year to be there and take some snapshots, as this event never fails to provide nice views, even when using only basic cameras as we did this time...

Incidentally this year the picture is adorned by the large dark spot from the "AR1944 group" (see older post) visible on the top view, close to the eastern (left) border of the solar disc, just about to cross to the farside after surviving a full revolution of the Sun : will it still be there after completing one more half revolution, that is some 2 weeks from now ?...
