Today’s H-alpha image shows the four active regions seen on NASA’s SDO image. Two regions on yesterday’s image, AR4382 and AR4380 have vanished, today’s AR4383 is very weak and likely to disappear soon. Yesterday’s prominence activity along the sun’s NE limb persists today, and the largest prominence is along the SW limb. There is also some lesser activity along the NW and E limbs.
The sunspot image below shows the four active regions just a little more clearly.
The galleries below showcase today’s major prominences.
