On a day when the clouds and rain returned to Oxford, the Sun had to develop another active region and sunspot!  So in my frustration, I went to work on two composites showing the morphology of AR2735 and AR2736 in hydrogen alpha and 540nm filters.  Here the results and apologies for the very bad quality of the resampled thumbnails caused by the odd shape of the image.  The quality of the full size image is much better but still a bit compromised because of the seeing conditions during the capture, but I like the way they came out.  Unfortunately the field of view in the 540nm images is too small to show the entire area in one image, but I show both regions on the same line for 2019-03-20.
