Bulletin

There are currently 8 sunspot regions visible on the solar disk. NOAA 2173 produced a long-duration M1.0 flare (peaking at 17:33UT) and 2 C-class flares. The CME related to the M1.0 flare was fairly narrow and directed to the southwest (away from Earth). Small sunspot region NOAA 2176 produced a C2 flare peaking at 03:51UT, and NOAA 2177 produced a C5.4 flare peaking at 05:54UT. The two most prominent regions, NOAA 2172 and compact NOAA 2175, remained quiet. Small delta structures are present in NOAA 2175 and NOAA 2177. Two 20-degrees long filaments are visible in the western solar hemisphere. Further M-class flaring is possible. Solar wind speed gradually slowed down from about 440 to 360 km/s. Bz oscillated between -5 and +4 nT. Geomagnetic conditions were quiet to unsettled and are expected to remain so.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 126, basierend auf 11 Stationen.
