It was a lovely, clear day for solar imaging. The H-alpha solar disk image shows a jet and small, arch prominence along the sun’s eastern and northeastern limbs. The wideband image shows a new sunspot group, AR3906, emerging from the east. NASA magnetic mapping of this new active region reveals a complexity conducive to solar flares with their consequences of radio blackouts and coronal mass ejections (CME) that can result in increased corona borealis phenomena.
The annotated sunspot cameo highlights the new group at AR3906.
Below, a cropped frame from the full disk, H-alpha image shows the filaments (prominences) and plages around sunspot group AR3901 near the center of the solar disk.
