What's The Large Dark Area On The Farside Of The Sun? 5-19-13 Stereo Behind Image

The big dark blob in the center. What is it?

It's an interdimensional portal don'tcha know? I am currently awaiting the planetoid fleet arrival of our Chicken Overlords:

I believe you are referring to "coronal cells"

The top images show coronal cells as viewed from above by STEREO-B (on the left) and SDO (on the right). Their diameters are about 18,000 miles.

The side-by-side nature of these open and closed magnetic fields – open in the coronal holes, and closed in the coronal cells – led to another scientific insight. In some of the movies, a large loop of solar material called a "filament" erupted from the adjacent filament channel. The coronal cells, with their closed field lines, disappeared and were replaced with a dark coronal hole and its associated open field lines.

Coronal hole

Coronal holes are areas where the Sun's corona is darker, and colder, and has lower-density plasma than average.

en.wikipedia.org...

sorry about wiki as a reference but I think its suitable in this situation.

Coronal Cells/Holes? So... nothing out of the ordinary then. Thanks!

It is indeed a coronal hole thats been tracked for days and was expected to throw some charged particles at us today causing atmospheric expansion, I was going to observe changes to the plotted jet stream if any but the bloody thing went quiet just as it went earth facing.

Edit: Sorry I just realised this was from one of the stereo satellites so I'm referring to the wrong hole! It is the same thing though!
