Today’s H-alpha image shows eight active regions and prominence activity along the W-NW, SW, and SE solar limbs.
The corresponding sunspot image shown below includes all of the sunspots that appear in today’s NASA SDO image. Region AR4366 is massive and has continued to be a source of geomagnetic disturbances, auroras, and phenomena related to its solar flares and coronal mass ejections (CMEs).
In the galleries below, the NW limb shows hair-like spicules; the prominence along the W limb shows strings of sun stuff streaming from the main eruption downward to the chromosphere. The remainder of the activity is typical.
