Sunspot 1112, located in the southeast quadrant, has been the source
of a giant filament that is currently stretching 400,000 km across the
surface of the Sun.
However, since 16. Oct 2010, there appears to be development of a
enormous circular ring which looks to be linking with the huge
magnetic filament of sunspot 1112. Most of today’s various wavelength
images of the Sun all show this feature over at the SDO (Solar
Dynamics Observatory) – NASA website.
SpaceWeather.com today reports:
"A vast filament of magnetism is cutting across the Sun’s southern
hemisphere today. A bright ‘hot spot’ just north of the filament’s
midpoint is UV radiation from sunspot 1112. The proximity is no
coincidence; the filament appears to be rooted in the sunspot below.
If sunspot flares, it could cause the entire structure to erupt. This
active region merits watching…"
