No processing other than combining three images of AR3590 from several days.

Compared to the wonderful images of AR3590 already uploaded to EarthSky.org, my contribution is pretty modest. What my image does do is to reveal the evolution of that incredible monster sunspot over a period of several days. One may wonder: (i) if AR3590 is preparing to do a coronal mass ejection?, (ii) if so, will it nail us?, and then (iii) will my lights go out? :)
