Solar Activity on 7-23-21

I took a diversion from the deep sky stuff I normally do the other day and imaged the Sun. One of the cool things about the sun is you can actually see these flares and prominences, with the right equipment, and they look just as impressive as the image shows - maybe more so. The equipment in my case is the Daystar Quark Ha Eyepiece solar filter attached to the Orion ED80.

Image 1 shows a massive flame coming out to the left and I put a scale image of Earth for comparison. Image 2 shows looping flares which are relatively low to the surface. Image 3 shows what could be classified as a prominence where the two protrusions are in contact with each other. If I was better at this (like Chuck's Astro) I would have made several separate images of this over an hour to make a video - a goal for some later date. The image also shows what looks like filaments, dark eyebrows, on the lower left. Also in this image is an ejection on the upper middle portion in the dark region. This third image was rotated 180 degrees so it was actually the bottom.
