Bulletin

Over the past 24 hours solar activity has been low. No significant flares have been recorded. No significant Active Regions (AR) or filament channels are present on the solar disk. A small, currently unnamed, AR is located near the the East Solar limb, it appears to be producing little activity. The greater-than 10 MeV proton flux was at nominal levels. An extended region of patchy coronal hole is currently extending from disk centre to the West solar limb. No Earth directed Coronal Mass Ejections (CMEs) have been detected.

Solar activity is expected to remain at low levels.

The solar wind speed has been decreasing from 550 to 450 km/s (DSCOVR) over the past 24 hours. The total magnetic field strength has fluctuated around 5 nT (DSCOVR). The Bz component has been fluctuated between -5 and +5 nT. Geomagnetic conditions ranged between Kp index 1-3 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. The abating solar wind wind conditions are related to the passing of a negative polarity coronal hole. However, the face of the solar disk is dominated by patchy coronal hole regions, which may enhance solar wind conditions for the next few days.

Geomagnetic activity is expected to be mainly quiet with short periods of activity.
