Details:
An interesting event took place on the Sun yesterday (23rd March) at 3.56pm Australian EST (5.56am UT).
There was quite a large spindly prominence ejecting from the south-western limb of the Sun. So I quickly took some colour images and by the time that I changed the setting to take some monochrome images at 4.07pm, the shape of the prominence had changed quite dramatically…in just 10 minutes!
I wanted to capture a close up of the ejecting plasma, so I quickly took the camera off the telescope to add a higher magnifying barlow lens, but when I looked again at 4.19pm it had completely evaporated…the whole prominence had just completely disappeared!
Now I asked myself, how could that happen? Perhaps the prominence was on the cusp of the limb and it just rotated out of view, or perhaps it was just very rarefied and it just disappears into space? Whatever the answer…it was just awesome to watch :-)
My images were taken with a Lund 80mm solar telescope and a Canon 700D SLR camera with a 2x Barlow lens. The colour image is a composite of two images, one for the solar surface and the other image for the fainter prominences; the monochrome image is not a composite. There were 30 images each fired off in rapid mode and stacked in RegiStack6 and processed in PS. (East is to the top of image and West to the bottom)
