Some regions start small and then peter out so it is possible that there can be gaps in AR numbers of those in view at any one time. Even with a 400mm telephoto lens the Sun takes up a small section of a photograph so the above are cropped sections. The most important safety feature used when directly observing the Sun is the use of a Solar filter which is designed to cut the brilliance down to a safe level.
