The Sun online and activity solar.26.10.2014



In the past 24 hours, Catania sunspot group 88 (NOAA AR 2192) produced two
X-class flares: X1.0 peaking at 17:08 UT yesterday and X2.0 peaking at
10:56 UT today. Neither of the flares seems to be associated with an
Earth-directed CME. The area of the Catania sunspot group 88 increases
again, and it maintains the beta-gamma-delta configuration of its
photospheric magnetic field, so we expect the flaring activity up to
X-level from this sunspot group. As the Catania sunspot group 88 is
currently situated in the western solar hemisphere, a major eruption in
this active region may lead to a proton event. A long filament in the
northern hemisphere is continuing its passage across the solar central
meridian. Its possible eruption may lead to an Earth-directed CME. The
Earth is currently inside a slow (around 370 km/s) solar wind flow with
slightly elevated (around 7 nT) interplanetary magnetic field magnitude.
The geomagnetic conditions are quiet and are expected to remain  so, with
isolated intervals of active (K = 4) geomagnetic conditions possible but
not very likely.

Veil Nebula


The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop (radio source W78, or Sharpless 103), a large but relatively faint supernova remnant. The source supernova exploded some 5,000 to 8,000 years ago, and the remnants have since expanded to cover an area roughly 3 degrees in diameter (about 6 times the diameter, or 36 times the area, of the full moon). The distance to the nebula is not precisely known, but Far Ultraviolet Spectroscopic Explorer (FUSE) data supports a distance of about 1,470 light-years.

The Hubble Space Telescope captured several images of the nebula. The analysis of the emissions from the nebula indicate the presence of oxygen, sulfur, and hydrogen. This is also one of the largest, brightest features in the x-ray sky.
