Here's a high-resolution 90 minutes of really dynamic action taken a few days ago on 19th March. Gas whirls around a vortex at measured speeds of at least 80-90km/s, then swings around to the left along the magnetic field lines, travelling up to 280,000km towards an active region (AR13258) on the solar limb. Much of the material slam-dunks into a drain at 120km/s into the Sun, while some continues around to complete a full whirling circuit! Also look for a small pretty fountain explosion at left about halfway through. Dancing fields of spicules provide a backdrop.
Some of the best seeing I've had for solar imaging - I needed pretty minimal sharpening throughout the 101 frames. I had wanted to image for longer, but with the hard drive filling up, I eventually lost the race between copying data to the external drive, clearing space while capturing >400GB of data.
A 90-minute inverted view timelapse of 101 frames. Each frame was taken with a 100mm refractor, Quark Chromosphere hydrogen-alpha filter and ZWO ASI174MM camera, 15s video (~2000 frames) every 50s, processed in Autostakkert, Registax, IMPPG, assembled in Photoshop and PIPP.
Clear skies all!
