Today’s H-alpha image shows low-level prominences along the sun’s SE and W limbs. There is a higher prominence along the NE limb, but it is too faint to appreciate without blowing out the image. Alas!
The sunspot image shows four of the five active regions seen in today’s NASA SDO imagery. AR4152 is too small and faint to see in my image; so, I have left a placeholder for it.
The main prominences appear in the gallery below.
