Astronomy Picture of the Day [1]Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2022 June 24 [2]See Explanation.

Filaprom on the Western Limb Image Credit & [3]Copyright: [4]Martin Wise Explanation: [5]A solar filament is an enormous stream of [6]incandescent plasma suspended above the [7]active surface of the Sun by looping magnetic fields. Seen against the solar disk it looks dark only because it's a little cooler, and so slightly dimmer, than the [8]solar photosphere. Suspended above the solar limb the same structure looks bright when viewed against the blackness of space and is called [9]a solar prominence. A filaprom would be both of course, a stream of magnetized plasma that crosses in front of the solar disk and extends beyond the Sun's edge. In this [10]hydrogen-alpha close-up of [11]the Sun captured on June 22, [12]active region AR3038 is near the center of the frame. Active region AR3032 is seen at the far right, close to the [13]Sun's western limb. As AR3032 is carried by [14]rotation toward the Sun's visible edge, what was once a giant filament above it is now partly seen as a prominence, How big is AR3032's filaprom? For scale planet Earth is shown near the top right corner.
