Solar Cycle 24 May Have Finally Begun

    The sun rotates, although with quit different speeds at the equator and the poles. For a period of 200 days, we will also get to see most of it (independently of the rotation). Unless one poses there is something very different about the side facing the Earth, no matter what "side" that is, the tendency should be quite clear. (I also think there are some space-based probes that are relevant here, but I am not sure whether any of them images the full "opposite side" of the sun regularly.)
