Bulletin

Active Region (AR) 2567 produced the largest flare, a B7.4 class flare peaking at 05:12 UT, AR 2565 (Macintosh class:Cao; Mag. type:Beta) has shown some evidence of flux emergence and cancellation in HMI magnetogram observations, this may increase flaring activity. All other 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 jumped from around around 550 km/s to 650 km/s at 21:00 UT yesterday. The total magnetic field strength has remained around 5 nT. The Bz component fluctuated around 0 nT, ranging between -5 and +5 nT. Geomagnetic conditions ranged between Kp index 2-3 (NOAA) and local K index 2-3 (Dourbes) over the past 24 hours. The increased solar wind speed reflects the arrival of a High Speed Stream (HSS) created by the large northern polar coronal hole in the Western hemisphere, if coupled with negative Bz we may experience enhanced geomagnetic activity over the next few days.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 080, basierend auf 23 Stationen.
