Side-by-side solar eruptions


Two coronal mass ejections (CMEs) expand side-by-side from the Sun and out into space in this movie, playing out in front of the ESA/NASA Solar and Heliospheric Observatory, SOHO, on 1-2 July 2013.

The shaded disc at the centre of the image is a mask in SOHO’s LASCO instrument that blots out direct sunlight to allow study of the faint details in the Sun’s corona. The white circle added within the disc shows the size and position of the visible Sun.

  1. That is the arm that holds the occulting disk which covers the Sun, for creating a artificial eclipse so that we can see the corona. It isn't "jet like." You're imagining that likeness. What you're seeing is just a product of poor data surrounding the arm. There is nothing jetting across the black line, as it may appear.

  2. It's a good idea to not assume clarity in your words. "Jet like" could have referred only to the shape and speed of the perceived movement, as such a word is normally used to describe such characteristics of movement. So it was unclear whether you thought there was actual movement or not.
    I did say that "It isn't "jet like."" But I was being technical and referring to it's actual likeness, instead of its perceived likeness. I'm sorry that was unclear.
