So far, my biggest prominence ever. Captured this on June 20, 2025 very early in the morning. When I started to scan, I kept seeing a white glance after the sundisk was away. I made sure the scans were wide enough to capture the phenomen. Unfortunately I could not compile the file using Inti as a part of the scanfield was cropped. With the help of Valerie Desnoux, I could change the settings of Inti resulting in a wider field.
The prominence is about 200.000km above the sun's "surface" and about 300.000km in length; remember this is the distance Earth-Moon.
Setting: Sol'Ex Pro 2nd Gen Slit and ASI678MM
Herschel Wedge
Software: SharpCap, Inti, CS4, DeNoise AI
