Bulletin

Only two C-class flares occurred during the past 24 hours: C2.2 flare peaking yesterday at 22:34 UT in the NOAA AR 2364 and C1.6 flare peaking today at 10:35 UT in the NOAA AR 2362. A strong B-class flare (B9.6) was produced by the NOAA AR 2361. We expect flaring activity on the C-level in at least one of these active regions, with an M-class flare being unlikely. The Earth is currently inside a slow solar wind flow with the speed around 350 km/s. The interplanetary magnetic field (IMF) magnitude is enhanced (up to 12 nT) in association with the apparent sector boundary crossing that occurred around 02:00 UT on June 7. This indicates the arrival of the interaction region between the slow and fast solar wind flows, with the fast flow emanating from the low-latitude coronal hole in the southern hemisphere. The geomagnetic conditions are currently quiet due to low solar wind speed and predominantly northward IMF in the strong field region, but a disturbance up to active level (K = 4) may occur due to the arrival of the fast stream later today or early tomorrow. A geomagnetic storm (K > 4) is unlikely.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 094, basierend auf 17 Stationen.
