Bulletin

Five C-class flares were observed since the last bulletin. The activity mainly originated from NOAA ARs 2108, 2109 and 2113. The largest flare was a C6.4 flare, peaking at 9:03 on July 13, originating from NOAA AR 2109, approaching the West limb. No Earth-directed CMEs were observed. C-class flares are expected, with an increasing chance for an isolated M-class flare. Due to the location of NOAA ARs 2108 and 2109, with increasing activity, a warning condition for a potential proton event is issued. Solar wind speed reached values between 350 and 400 km/s. The magnitude of interplanetary magnetic field increased from 5 to 9 nT with a currently positive Bz component. No clear signatures of a shock arrival of the July 9 CME were observed yet. Geomagnetic conditions have been quiet to unsettled. This is expected to remain so till the possible arrival of a glancing blow of the July 9 CME, which might increase geomagnetic activity.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 069, basierend auf 07 Stationen.
