The solar activity has been quiet over the past 24 hours. The visible solar disc is spotless and no flare has been recorded. Quiet flaring conditions are expected for the next 24-hour period.

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.

On April 8, the solar wind speed was fluctuating between 340 and 370 km/s, the total magnetic field strength remained below 5 nT, and the Bz component was ranging between -5 and +4.5 nT. On April 9 around 00:00 UT, the solar wind measurements indicated the onset of a Corotating Interaction Region (CIR) announcing the soon arrival of the solar wind High Speed Stream (HSS) associated with the Coronal Hole (which has crossed the central meridian on April 5). The wind speed shows a gradual increase from the nominal values to the current values ranging from 460 to 470 km/s, the total magnetic field strength reached 8.8 nT and Bz component -5.5 nT. The enhanced solar wind conditions are expected to persist for the next 24-hours period and until the influence of the HSS associated with the coronal hole decay.

Geomagnetic conditions ranged between Kp index 1-3 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. Due to the ongoing enhancement of the solar wind, disturbed Geomagnetic conditions are expected, minor to moderate geomagnetic storms cannot be excluded, especially if Bz component remains negative for long period of time.
