It was overcast most of the day; still, I managed to get some respectable solar AVI movies to process. Today’s comparison images of the solar disk show very active prominences along the southeastern solar limb (H-alpha image on the left) and new sunspot groups emerging from the eastern limb (image on the right).
The complex prominence visible along the sun’s southeastern limb extends onto the disk where it is visible as a filament. It has a distinctly 3-D appearance at the transition zone.
The annotated sunspot cameo below shows the complex sunspot group AR3883 that has been the source of many solar flares the past 24hrs. These electromagnetic discharges have been strong enough to cause significant radio communication disruptions.
