"Super Sunspot".
Sunspots are temporary phenomena on the photosphere of the Sun that appear visibly as dark spots compared to surrounding regions. They are
caused by intense magnetic activity.  They usually appear as pairs, with each sunspot having the opposite magnetic pole to the other.  The contrast
with the surrounding material at about 5,780 K (5,500 °C) leaves them clearly visible as dark spots.  Yet, if the sunspot were isolated from the
surrounding photosphere it would be brighter than the Moon.
