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.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 135, sur la base de 12 stations.
