Bulletin

The Sun is spotless and did not produce any flares in the past 24 hours. The chance for a C flare in the next 24 hours is estimated at only 1%.

No Earth-directed Coronal Mass Ejections (CMEs) were observed in available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours.

Solar wind speed near Earth as registered by DSCOVR varied between about 315 and 390 km/s in the past 24 hours. The direction of the Interplanetary Magnetic Field (IMF) changed from towards the Sun to away from the Sun around 10h UT on March 16, and its magnitude varied between about 0 and 8 nT. Bz was never below -5 nT. Quiet solar wind conditions are expected in the next 24 hours.

Quiet to unsettled geomagnetic conditions (K Dourbes between 1 and 3; NOAA Kp between 1 and 3) were registered in the past 24 hours. Quiet to unsettled geomagnetic levels (K Dourbes < 4) are expected on March 16, 17 and 18.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 000, sur la base de 28 stations.
