Bulletin

Over the past 24 hours solar activity has been very low, there have been no C, M or X-class flares recorded. All Active Regions (AR) have remained stable, showing small amounts of flux emergence. A small Coronal Hole (CH) is currently located near disk center. There were no Earth directed Coronal Mass Ejections (CMEs) observed over the past 24 hours. Solar activity is expected to remain low with a chance of C-class flares.

The solar wind speed has been steadily decreasing over the past 24 hours, from around 480 km /s to around 360 km /s. The total magnetic field has remained stable around 5 nT over the past 24 hours. The Bz component has oscillated between -5 nT and +6 nT over the past 24 hours. Geomagnetic conditions have been mainly quiet over the past 24 hours (NOAA Kp 1-3, local K Dourbes 1-3). A small coronal hole (CH) currently located near solar disk center may enhance geo-activity in the next few days.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 058, sur la base de 06 stations.
