Bulletin

There are currently 11 sunspot groups visible on the solar surface. NOAA 2108 and 2109 are the most prominent regions. NOAA 2108 increased its sunspot area and developed a weak delta in its trailing main spot. NOAA 2109 also developed a weak delta, located in the eastern portion of the main (leading) spot. Only three C-class flares were reported. The strongest, a C4.0 peaking on 6 July at 00:25UT, had its source in NOAA 2109, whereas NOAA 2108 produced a C3.5 flare peaking at 07:00UT. C-class flares are expected, with a chance on an M-class flare from NOAA 2108 and 2109. Solar wind speed declined from 290 to 250 km/s until 09:30UT, when a sudden increase back to 290 km/s was observed. Bz varied the entire period between -6 and +4 nT. Geomagnetic conditions were quiet and are expected to remain so as Earth is crossing different sectors of the heliospheric current sheet.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 135, gebaseerd op 12 stations.
