some people have experienced a sun which is perfectly round, with no glow, just a big orange ball up in the sky with sharp edges.
your sun has a glow, a halo if you will... a corona.
some people are not so lucky, but i think there are fixes.
next time you play the game look at the sun and hit shift page down a few times and you will see what i mean.
(or maybe its control page down).
