Astronomy Picture of the Day -- Solar Flare from a Sharper Sun
NASA ^ | November 22, 2014 | (see photo credit)

Explanation: Solar active region AR2192 was the largest recorded sunspot group of the last 24 years. Before rotating off the Earth-facing side of the Sun at the end of October, it produced a whopping six energetic X-class flares. Its most intense flare was captured on October 24 in this stunning view from the orbiting Solar Dynamics Observatory. The scene is a color combination of images made at three different wavelengths of extreme ultraviolet light; 193 angstroms shown in blue, 171 angstroms in white, and 304 angstroms in red. The emission, from highly ionized Iron and Helium atoms, traces magnetic field lines looping through the hot plasma of the Sun's outer chromosphere and corona. Beneath, the cooler solar photosphere appears dark at extreme ultraviolet wavelengths. The exceptionally sharp composite image has been processed with a new mathematical algorithm (NAFE) that adapts to noise and brightness in extreme ultraviolet image data to reliably enhance small details.

Switching to another channel.
I've got sunspots.

In my eyes, indisposed in disguise as no one knows
Hides the face, lies the snake and the sun in my disgrace
Boiling heat, summer stench, ‘neath the black the sky looks dead
Call my name through the cream and I’ll hear you scream again

Black hole sun,
Won't you come
And wash away the rain?
Black hole sun,
Won't you come?
Won't you come?
Won't you come?

A great song.

Stuttering
Cold and damp
Steal the warm wind tired friend.
Times are gone
For honest men
Sometimes far too long for snakes

In my shoes
Walking sleep
And my youth I pray to keep.
Heaven send
Hell away
No one sings like you anymore
