Bulletin

Over the past 24 hours solar activity has been very low. No significant flares have been recorded. Active Region (AR) 2565 (Macintosh class:Hax; Mag. type:Alpha) produced the largest flare, a B8.7 class flare peaking at 21:02 UT yesterday. All ARs appear relatively stable. No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 hours. There is currently a large +ve polarity trans-equatorial northern polar coronal hole in the Western hemisphere. Solar activity is expected to remain low over the next 24 hours, with a reasonable probability of C-class flares and a low probability of M-class flares. The solar wind speed has fluctuated around 550 km/s over the past 24 hours. The total magnetic field strength has fluctuated around 5 nT. The Bz component fluctuated around 0 nT, ranging between -5 and +5 nT. Geomagnetic conditions ranged between Kp index 2-4 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. The large northern polar coronal hole in the Western hemisphere may increase solar wind speeds over the coming days, if coupled with negative Bz we may experience enhanced geomagnetic activity over the next few days.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 059, basierend auf 19 Stationen.
