Today’s H-alpha image shows further development of the prominences that we documented yesterday along the sun’s western limb.
The annotated sunspot image below shows six active regions. Two additional regions, AR4123 and AR4124, are visible in todays’ NASA SDO image but are too faint to see here.
Today’s prominence cameo covers most of the sun’s western limb. In the NW, a tall pillar of sun stuff towers over the chromosphere as it rains material back to the sun. In the SW, two major structures project sun stuff into the corona with some of it arching back to the chromosphere.
