Solar activity was very low with only a single B level flare. There are no spotted regions on disk and Solar flaring is expected to remain below C level over the next days.

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

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to stay at nominal levels. The greater than 2 MeV electron flux was at background levels the past 24 hours and is expected to remain so.

Solar wind conditions continued to enhance over yesterday afternoon. Solar wind speed reached a peak of around 500km/s around 19UT before starting a gradual decline to under 400 km/s currently. Total magnetic field reached to 12nT early in the period with a variable Bz with peaks down to -9nT. Total magnetic field is currently back at a nominal 5nT level. The magnetic field phi angle was variable but now steady in the negative sector again. Solar wind conditions are expected to remain close to nominal over the next 24 hours with more significant enhancements expected by April 11, due to the low latitude extension of the southern polar coronal hole that has transited the central meridian in the past days.

Geomagnetic conditions were quiet to active (NOAA Kp 1-3 and local K Dourbes 0-4) in response to the moderate Solar wind enhancements. Unsettled conditions are expected over the next 24 hours and by April 11 are active conditions expected with possibly minor geomagnetic storm periods.
