There are currently 9 sunspot groups visible on the solar surface. NOAA 2104, 2108 and 2109 are the most prominent regions, but do not have magnetic delta’s. This may change for NOAA 2108 and 2109, as these groups have shown a gradual increase in sunspot area over the last 24 hours. Four C-class flares were observed. NOAA 2108 produced 3 of them, including the largest event being a C4.2 flare peaking at 14:39UT (4 July).
C-class flares are expected, with a chance on an M-class flare from NOAA 2104, 2108 and 2109.
Solar wind speed declined from 330 to 290 km/s, with Bz varying between -1 and +3 nT. Geomagnetic condions were quiet and are expected to remain so.
