Sun takes little less than a month to complete one rotation, and as it rotates we can see how Sun changes, sometimes it changes dramatically and sometimes it has only small difference.

The following video shows Sun rotating over the period of one month - January. The larger image of Sun's chromosphere is shown in ultra-violet light. Other images are showing relatively rare iron atoms located at different heights of the corona in X-Ray. All of them are false-colored to show the difference.
Check the beautiful Sun in the below video.
