Bulletin

Over the past 24 hours solar activity has been quiet. A C1.0 flare was produced by Active Region (AR) 2712 peaking at 11:00 UT yesterday. The region was located close to the solar limb. No Earth directed Coronal Mass Ejections (CMEs) have been detected. There are no significant coronal holes or filaments. Solar activity is expected to remain low over the next 24 hours with a low probability of C-class flares. The solar wind speed has fluctuated between 460 and 370 km/s over the past 24 hours. The total magnetic field strength has increased from around 3 to 11 nT, but now appears to be declining again. The Bz component has fluctuated around 0 nT, but was mainly negative yesterday afternoon, from 16:00 UT, reaching -9 nT before turning positive at 01:00 UT this morning, reaching 10 nT. Geomagnetic conditions ranged between Kp index 1-4 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. with the peak of 4 coinciding with the negative Bz yesterday afternoon. Geomagnetic conditions are expected to be mainly quiet with a small chance of activity while the magnetic field strength is enhanced.
