Looks like a combination of sun spots and filaments (possibly compressed areas of the photosphere) exacerbated by the filter used to take the photo. Looks like the chromosphere/corona is covering part of it.
During the solar maximum it is not unusual to see large dark areas in the Sun. During the solar minimum it would be.
I look at it like this; If the Sun is going to go there is not anything we can do about it, so why worry? Personally, if it is going to go, I hope it does it before April 15.
