No doom and gloom here. Just curious as to why no one can explain a triangular opening on the Sun. Here is today's photo. Notice how it has rotated
since the first sighting, to now.
But it has been explained:
It's not really a hole (in the sense that a section of the sun is missing and you are looking into the sun's interior).
It's an area of the sun who's magnetic loops are not closed, but trailing out.
The plasma density is lower here, so the temps are cooler here compared to the area around it.
It is only visible in the extreme ultra violet frequency range (which is what the images show).
As for it looking like a triangle: coronal holes have taken the form of many shapes that our eyes see. Phage posted a long list of images last year
showing many other "triangle" images, and other coronal holes that looked like many other things (the "duck" one stuck out to me).
None of the images show a perfect triangle either (3 straight sides, with 3 angles that form 180 degrees). Instead, our mind and eyes equate it with a
general shape as we want something to look like something familiar.
For example, your latest image looks more like a arrow head (complete with fin at it's base) than it does just a regular triangle to me.
If it really was a "hole" in the sun, then it would be visible all across the entire spectrum of light. IR to EVU. Not just in the EVU
