Bulletin

Over the past 24 hours solar activity has been low. No significant flares have been recorded. There are no significant Active Regions (AR) on the solar disk. A small patchy coronal hole passed the central meridian a couple of days ago, and has the potential to increase solar wind speeds at the Earth over the next couple of days. 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. The solar wind speed has fluctuated between 350 and 400 km/s over the past 24 hours. The total magnetic field strength has fluctuated around 2 nT. The Bz component was largely positive, fluctuating around 0 nT. Geomagnetic conditions ranged between Kp index 0-1 (NOAA) and local K index 0-2 (Dourbes) over the past 24 hours. Geomagnetic conditions are expected to be quiet.

Today's estimated international sunspot number (ISN): 000, based on 31 stations.
