Here are today’s solar images taken from Al Sadeem Observatory, May 21, 2017.
The sky was clear and seeing was fair, due to light to moderate northwesterly breeze, at the time these images were taken.
The Sun has been spotless indicating a generally very low solar activity for 4 consecutive days already. It is currently transitioning towards the solar minimum, the period in the roughly 11-year solar cycle when less solar activity is expected. This was anticipated to be reached between 2019 and 2020. Basically, the relatively cool and dark areas on the Sun’s photosphere, known as sunspots, appear and vanish due to violent twisted magnetic field interactions with its surface plasma.

The Sun in H-alpha. It has been quiet, with no significant solar activity observed in the past few days except for some prominences seen in the upper and bottom portions of this image.
Note that the circular grayish spot seen on the disk (bottom left portion) is NOT something special, but an output of lens contamination.
