Bulletin

Over the past 24 hours solar activity has been low. No significant flares have been recorded. There are currently no significant Active Regions on the solar disk. A region of low latitude negative polarity patchy coronal hole passed solar disk central meridian two days ago. 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 and a low probability of M-class flares. The solar wind speed has decreased from 375 and 325 km/s over the past 24 hours. The total magnetic field strength has fluctuated around 5 nT. The Bz component fluctuated around 0 nT, ranging between -5 and +5 nT. The region of low latitude negative polarity patchy coronal hole that passed solar disk central meridian two days ago and may enhance solar wind speeds at Earth over the next couple of days. Geomagnetic conditions ranged between Kp index 1-2 (NOAA) and local K index 1-2 (Dourbes) over the past 24 hours. Geomagnetic conditions are expected to be quiet to unsettled.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 17 stations.
