Bulletin

Over the past 24 hours solar activity has tendency to increase with respect to the previous day. A largest flare was a long duration C2.8 flare has produced by Active Region (AR) 2529 (Exi:Beta), which peaked at 13:42 UT yesterday. 7 more C class flares were produced by this AR 2529 over the past 24 hours. There are two ARs currently on the solar disk; AR 2529 and AR 2528(Axx:Alpha). AR 2528 is going to move over the solar limb in the next 24 hours, while one returning region will appear at the East limb within next 24 hrs. No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 hours. Solar activity is expected to remain moderated over the next 24 hours with a high probability of C-class flares. However there is currently a negative coronal hole (CH) transiting the central meridian, as the consequence a minor storming can be expected probably around 12 April. The solar wind speed has fluctuated between 320 to 380 km/s over the past 24 hours. The total magnetic field strength remained stable with the magnitude varying between 4 and 6 nT. The Bz component remained mainly positive, varying between +5 and -4 nT. Geomagnetic conditions ranged between Kp index 1-3 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. Geomagnetic activity is expected to remain low within next 2 days. However a minor geomagnetic storm can be expected around 12 of April due to a negative coronal hole transiting the central meridian.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 026, basierend auf 21 Stationen.
