Bulletin

Over the past 24 hours solar activity has been low. there were no significant flares and all Active Regions (AR) have shown low levels of activity. No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have 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 slowly decreasing from 370 to 350 km/s over the past 24 hours. The total magnetic field strength has been increasing from around 4 nT to 6 nT. The Bz component fluctuated around 4 nT, and been mainly positive. Geomagnetic conditions ranged between Kp index 0-2 (NOAA) and local K index 0-3 (Dourbes) over the past 24 hours. A small equatorial, positive polarity coronal hole is currently located in the Western hemisphere and the resultant High Speed Stream (HSS) may enhance solar wind speeds around the end of today (22-Oct-2016). Geomagnetic conditions are expected to be unsettled over the next 24 hours.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 028, sur la base de 16 stations.
