A very hot sunny day again - these images taken mid morning.
First image at 540 nm to show the sunspots. The active regions are numbered in the first image.
Second and third images are at 656 nm (Halpha) to show the prominences, filaments and flares etc. These align with the first image.
All are single exposures with a Canon 550d.
Thanks for viewing.
