Huge Filaprom, 2015 (digital photo)

Creator: Gabriel Octavian Corban This image shows a very large filaprom: a prominence seen partially over the Sun's disc as a filament. You could fit about 150 Earth's side-by-side along its length. The image was obtained using a DayStar Quark H-alpha Chromosphere model filter, at an effective pixel scale of 0.31 arcseconds/pixel. "This image has an extraordinary three-dimensional feel to it. The interplay of the bright and dark regions is absolutely superb. With the dark filament turning into a delicate, twisting prominence at the limb, you really get the sense that this vast ribbon of plasma is looming over the smaller structures below."
