INFO FROM SIDC – RWC BELGIUM 2014 Oct
Four low-level C-class flares were recorded. The strongest was a C1.9
peaking at 22:15UT and produced by NOAA 2172 from behind the west limb. The
x-ray background flux has decreased below the C1-level. There are currently
8 sunspot groups visible on the solar disk. Most of them are fairly simple,
and contain a filament or are close to one. Further C-class flaring is
expected. A 20-degrees long, thin, but dynamical s-shaped filament has
rounded the southeast limb. This area seems to have been responsible for a
filament eruption on 03 October between 03:00 and 04:30UT. The associated
CME was not directed to Earth.
Solar wind speed increased from about 330 to 370 km/s. Bz was initially
fluctuating around 0 nT untill about 05:00UT, when it gradually increased
to the current +10 nT. Geomagnetic conditions were quiet to unsettled, and
are expected to remain so, with locally an active episode possible.

The only C-class event of the period was a C1 flare peaking at 09:54UT and
produced by NOAA 2178. The 7 groups currently visible on the solar disk
have a relatively simple magnetic configuration and have been quiet.
Numerous filaments are present on the solar disk, but they are mostly small
and quiet. There remains a chance on an C-class flare. No obvious CMEs were
observed during the period.
A corotating interaction region has influenced the solar wind since late on
3 October. Around 17:00UT on 4 October, the direction of the IMF turned
towards the Sun, and solar wind speed peaked near values of 480 km/s early
on 5 October. Bz was mostly positive, fluctuating between -5 and +10 nT
during the latter half of the observation period. Geomagnetic conditions
were quiet to unsettled and are expected to remain so.
NGC 7635, also called the Bubble Nebula, Sharpless 162, or Caldwell 11, is a H II region emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The “bubble” is created by the stellar wind from a massive hot, 8.7 magnitude young central star, the 15 ± 5 M☉ SAO 20575 (BD+60 2522). The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow. It was discovered in 1787 by William Herschel. The star SAO 20575 or BD+602522 is thought to have a mass of 10-40 Solar masses.
With an 8 or 10-inch (250 mm) telescope, the nebula is visible as an extremely faint and large shell around the star. The nearby 7th magnitude star on the west hinders observation, but one can view the nebula using averted vision. Using a 16 to 18-inch (460 mm) scope, one can see that the faint nebula is irregular, being elongated in the north south direction.
