Bulletin

There are currently 9 sunspot groups visible, with NOAA 2104 and 2109 the largest and magnetically most complex regions. Only 1 C-class flare was recorded. This C2.4 flare peaked at 05:37UT and had its source in NOAA 2109. A long filament near the west limb became unstable and mostly disappeared overnight (3-4 July), however no obvious CME was observed. Some subflaring activity in the long filament near NOAA 2106 was observed around 09:30UT. C-class flares are expected, with a chance on a strong flare from especially NOAA 2104 and 2109. Solar wind speed remained fairly constant around 350 km/s. Bz was mostly negative between 21:00 and 08:00UT, and positive for the rest of the period. Its value varied between -5 and +4 nT. Quiet geomagnetic conditions were observed and are expected to remain so.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 131, basierend auf 16 Stationen.
