Bulletin

Over the past 24 hours solar activity has been Low. No significant flares have been recorded. There are currently no ARs on the solar disk, although a new AR will rotate into view tomorrow. No Earth directed Coronal Mass Ejections (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 low probability of C-class flares. The solar wind speed has been decreasing from 550 and 340 km/s. The total magnetic field strength has fluctuated around 3 nT. The Bz component has fluctuated around 0, ranging between -3 and +3 nT. Geomagnetic conditions ranged between Kp index 1-2 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. Small enhancements in geomagnetic activity may be experienced due to a region of patchy coronal hole located near disk centre a couple of days ago. Geomagnetic conditions are expected to be quiet to active.

Today's estimated international sunspot number (ISN): 000, based on 22 stations.
