説明 | A Prominence is an arc of plasma lifted above the Sun's surface by intense magnetic fields at the very edge of the Sun (the limb) - It appears light (and hot) against the dark background of space. A Filament is exactly the same, but seen over the face of the Sun so that it appears dark (and cold) against the bright, hot photosphere. As the Sun rotates, Proms become filaments. There is a massive "hedgerow"prominence on the Sun's Eastern limb which is now rotating round to become a filament.This was a very rushed image taken between clouds. Little time to focus or adjust imaging parameters.Celestron 1000/102mm refractorSolarscope DSF 70mm filtersSkyris 274m CCD cameraIoptron ZEQ25GT mount |
