What is this strange ring that has been developing on the Sun during
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
However, today, 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
What concerns me is that if indeed this is a huge magnetic filament nearly
encircling the entire Sun, it is now currently directly facing the
Earth. If sunspot 1112 does erupt, could the entire filament explode
into a massive CME?
This particular phenomenon will be all over in a few days as it rotates
around the Sun, but it serves to remind us that there are more and more events
happening on the Sun as we transit into the next solar cycle maximum (peaking ~
2012 into 2013).
