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.

The Earth is currently into the fast solar wind speed associated with the equatorial coronal hole (which has crossed the central meridian on April 05). The solar wind speed has increased from around 560 to 610 km/s over the past 24 hours. The total magnetic field strength ranged between 4 and 6.5 nT. The Bz component was ranging between -5.7 and +4 nT being many negative. The enhanced solar wind conditions are expected to persist for the next 24-hour period and until the influence of the HSS associated with the coronal hole decay.

Geomagnetic conditions have been active over the past 24 hours. An isolate minor storm with Kp index 5 (NOAA) was observed at 00:00 UT on April 11 due to Bz component being negative for a prolonged period. The local K index 4 (Dourbes) was observed about the same time. Due to the ongoing enhancement of the solar wind, unsettled to active geomagnetic conditions are expected. Isolated minor geomagnetic storms cannot be excluded, especially if Bz component remains negative for a long period of time.
