The Equinox Sun: September 22, 2014

The weather was typical Indiana early Fall: clear, cloudless skies of the deepest blue, but also very turbulent. Seeing was poor and it was hard to get good contrast on the images, so these pix are mostly for record purposes.


The first pic is an inverted image of the area around the AR 2172 complex; below is a more detailed closeup of part of AR2172 itself.


AR 2174, on the opposite side of the disk, is an area of bright faculae in white light; in H-Alpha, it looks fairly quiescent.
