Today’s H-alpha image shows prominences along the NE, SE, NW, and SW solar limbs. Below, a bright plage associated with AR4207 in the NW ends in one of those prominences.
The corresponding sunspot image shows only four active regions since AR4212 has disappeared to the sun’s far side. Note the plume of sun stuff just north of AR4207.
Today’s largest prominences appear in the gallery below.
