Skrót wiadomości

Over the past 24 hours solar activity has been low. The largest flare was a B2.7 class flare. Active Region (AR) 2738 (Mcintosh class:Hsx; Mag. type:Alpha) has been most active, producing several B-class flares, including the B2.7 class flare, which peaked at 06:25 UT. Former AR 2737 is approaching the west solar limb, and has shown little activity. No significant filament channels have been seen on the solar disk. No Earth directed Coronal Mass Ejections (CMEs) have been detected. There are no significant low latitude coronal holes on the solar disk. 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 region is currently close to the east solar limb, and it is difficult to assess the associated magnetogram data. The solar wind speed has fluctuated between 375 and 400 km/s over the past 24 hours, but jumped up to 450 km/s this morning. The total magnetic field strength has slowly increased from around 3.5 to approximately 7.5 nT. The Bz component fluctuated around 0 nT, ranging between -8 and +7 nT. Geomagnetic conditions ranged between Kp index 1-4 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. Kp reached 4 this morning due to the Bz reaching -8 nT for a short period. Geomagnetic conditions are expected to be quiet with a small possibility of active conditions.
