Castiel, a summary
I can’t believe I just did this!! I…me!! Miss I-Have-Trouble-Braiding-My-Hair. I know it’s not perfect, but to me it kicks ass! I kind of like it...

Twisting Solar Eruption
On May 3, 2013, a magnetic “active region” on the Sun erupted in a small solar flare. This triggered a towering prominence, a huge blast of superheated plasma into space. This footage, created from ultraviolet observations by NASA’s Solar Dynamics Observatory, shows the event, compressing three hours of real time into 19 seconds.

NASA SDO - Dark Flag Rising
A long-lasting double flare and a coronal mass ejection erupted from the Sun over a five-hour period (February 5-6, 2013). The eruptive plasma was cooler than the surface and denser, causing it to appear almost like a flag unraveling. Following the event the magnetic field lines above the source area appear as coils as they try to reconnect themselves. The event also seemed to disrupt a filament to its left, highlighting its edges in white light. Images were taken in extreme ultraviolet light.

The solar eclipse of July 28, 1851 is the first correctly exposed photograph of a solar eclipse, using the daguerreotype process.
Berkowski made this first solar eclipse photograph at the Royal Observatory in Königsberg, Prussia (now Kalinigrad, Russia)
NASA Scientists Observe the Sun in Different Wavelengths

Today’s Sun; September 10, 2012 during the eclipse. I call this one Earth rising.
Earth is moving from the bottom up, eventually covering the entire Sun. This is normal part of the eclipse season.

A look at the September 9, 2012 Earth eclipse in four different wavelengths.
Top row shows the Earth moving in at 06:33 UT while the bottom row shows Earth moving out at 07:22 UT.
From left to right we have 193 (2.25 million Fahrenheit), 211 (3.6 million Fahrenheit), 304 (90,000 Fahrenheit) and 171 angstrom (1.8 million Fahrenheit).
Due to my orbit (inclined geosync orbit) I get to see Earth twice a year around the equinox time. It’s a normal and planned occurrence in this life of this sun observing spacecraft.
Oh, and why isn’t the edge of Earth sharp? That’s because of Earth’s atmosphere and my abilities to see light through it.

Here is another look at today’s eclipse where Earth moved in between my telescopes and the Sun.
Why the different colors?
This is a 3 image composite. The three pictures are put on top of each other. Since the instrument can’t take a picture of all wavelengths at the very same time, different wavelengths images get taken slightly later or earlier.
If you look on the bottom left you can see the times the three pictures were taken.
94 at 06:43:38
335 at 06:43:52
193 at 06:43:55
So the 17 seconds in between the 1st and the 3rd image is enough time for Earth to block more of the Sun.

Oh, hai today’s sun. Why you so angry?
