Bulletin

Solar activity has been low, NOAA AR 2373 has just rotated into view and has the potential to produce several flares, it has already produced 3 C-class flares in the past 24 hours, the largest being a C1.9 flare peaking at 17:14 UT on 2015-06-28. The previously active AR 2371 has rotated over the West limb, but produced the largest magnitude flare in the past 24 hours, a C2.2 flare peaking at 00:36 UT on 2015-06-29. Other recurrent active regions are rotating into view now and may increase solar activity in the coming hours. Proton levels are still declining and are now below 5 pfu. The solar wind speed has slightly decreased over the past 24 hours, and has varied between 350 km/s to 480 km/s. The total magnetic field has been around 6 nT with small variations ranging from 4 to 8 nT, and the Bz component has fluctuated from positive to negative, between +6 and -5 nT over the past 24 hours. Geomagnetic conditions ranged between Kp index 2-3 (NOAA) and local K index 1-4 over the past 24 hours. There were no significant CMEs over the past 24 hours.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 034, basierend auf 17 Stationen.
