April 8, 2019: H-alpha lunchtime with massive sunspot

[michael.h.f.wilkinson]

Just had a nice look at the sun in H-alpha, during my lunch break. The new sunspot is turning out nicely, with quite a bit of plage around it, especially prominent using double-stacking. There is another plage area near the western limb, around the 9 o'clock position. A fairly large prominence can be made out around the 10 o'clock position. Quite a bit of activity, and I really hope I get a chance at imaging this big new AR. A couple of students and staff members came around to have a look. Great fun all round

Almost as interesting in white light. With lots of fine surface detail. Well worth a look.
