Bulletin

Over the past 24 hours solar activity has been low. There have been no significant flares. Active Region (AR) 2738 (Mcintosh class:Cho; Mag. type:Beta) has been quiet, the region has shown some evidence of flux emergence and cancellation in HMI magnetogram observations, this may increase flaring activity. No significant filament channels have been seen on the solar disk. No Earth directed CMEs have been detected. The greater- than 10MeV proton flux remained at background levels over the past 24 hours. Solar activity is expected to remain low over the next 24 hours with a reasonable chance of a C-class flare from AR 2738. The solar wind speed has decreased from 425 to 375 km/s over the past 24 hours. The total magnetic field strength has fluctuated around 3 nT. The Bz component has fluctuated around 0 nT, ranging between -2 and +3 nT. Geomagnetic conditions ranged between Kp index 0-2 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. Geomagnetic conditions are expected to be quiet.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 014, basierend auf 21 Stationen.
