It really surprised me as I watched AR11726 at CaK wavelengths on the laptop screen whilst imaging on saturday, the whole region was actively crackling away with Ellerman bombs erupting on a continuous basis. These micro solar flares are named after Ferdinand Ellerman who studied these solar blasts in the early 20th century. They appear as bright explosive flashes as two oppositely charged ion flows meet in the solar photosphere. I shot this with a cadence of 20 seconds giving me an avi of just less than 600 frames, of this I stacked the best 50 for each frame of the animation. The image above is made up of 34 frames and represents just over 11 minutes in the life of AR11726. It was shot with the 100mm refractor at 1600mm focal length using a homebrew CaK filter and a DMK31 camera. The link below will take you to the full length animation which is over 70 frames long and represents 25 minutes in the life of this active region
