The solar activity has been quiet over the past 24 hours. The active region (NOAA 2704, Mcintosh class: Axx, Mag. type: Alpha) has decayed. No significant flare has been recorded. The flaring conditions are expected to be quiet for the next 24-hour period with a very small chance of C-class flare.
No Earth directed Coronal Mass Ejection has been observed. The greater than 10 MeV solar protons flux remained at nominal levels over the past 24 hours and is expected to remain so.
The solar wind conditions are showing an ambient-background and slow solar wind speed regime. The solar wind speed has decreased from around 450 to 345 km/s over the past 24 hours. The total magnetic field strength remained below 5.5 nT, and the Bz component was fluctuating between -3.5 and +2.5 nT. Solar wind conditions are expected to remain in the slow speed regime.
Geomagnetic conditions have been mostly quiet over the past 24 hours, and ranged between Kp index 1-2 (NOAA) and local K index 0-3 (Dourbes). The geomagnetic conditions are expected to remained quiet for the next period.
Today's estimated international sunspot number (ISN): 007, based on 16 stations.
