Bulletin

NOAA 2381 developed rapidly and has some mixed magnetic polarities. It was the source of six C-class flares and the strongest event of the period, an M1.0 flare peaking at 08:44UT. The five other sunspot regions are small and quiet. No Earth-directed coronal mass ejections have been observed.

C-class flaring is expected, with a good chance on a low-level M-class flare.

Earth is still under the influence of the high speed, low density stream of the negative coronal hole (CH). Solar wind speed varied mostly between 500 and 600 km/s, with Bz varying between -6 and +6 nT. Episodes with active geomagnetic conditions were recorded during the early hours of 06 July. A positive equatorial CH is approaching the central meridian.

Quiet to unsettled geomagnetic conditions are expected, with a good chance on an active geomagnetic episode.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 105, basierend auf 21 Stationen.
