The solar activity has been quiet over the past 24 hours. The visible solar disc is spotless and no flare has been recorded. A bipolar region shortly developed around noon on April 09 (near the central meridian, around latitude 30 South), but gradually decay. 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 under the influence of the enhanced 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 470 to 560 km/s over the past 24 hours. The total magnetic field strength ranged between 5 and 8.5 nT with a peak of 9.5 nT at 02:25 UT on April 10. The Bz component was ranging between -8.2 and +7.5 nT with prolonged periods of southward direction between 13:10 and 21:30 UT on April 09, and between 01:45 and 09:28 UT on April 10. 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 have been active over the past 24 hours. Kp index 4 (NOAA) was observed at 21:30 UT on April 09, and between 05:30 and 08:00 UT on April 10, which corresponds to the Bz component being negative for two prolonged periods. The local K index 4 (Dourbes) was observed between 22:00 and 23:00 UT on April 09. Due to the ongoing enhancement of the solar wind, active Geomagnetic conditions are expected, isolated minor geomagnetic storms cannot be excluded, especially if Bz component remains negative for long period of time.
