This is a single-frame H-alpha image of the Sun captured on June 13, 2026, using my 60mm Lunt solar telescope in single-stack mode, without a 2X Barlow.
The large prominence along the lower-left edge is what immediately caught my attention. It extends outward from the solar limb with a broad, arched structure and visible internal detail. Using the scale that approximately 110 Earths could fit edge to edge across the diameter of the Sun, this prominence is estimated at approximately 28 Earths across from left to right.
The solar disk also shows visible H-alpha surface texture, with an active region on the right side of the image.
Capture details: ZWO ASI294MC Pro camera, captured with SharpCap 4.1, RGB24 color space, 1920 × 1200 capture area, gain 72, exposure 12.365 ms, single-frame snapshot.
