Five sunspot groups were reported by NOAA today. However, the only C-class flare observed during the past 24 hours (C1.3 flare peaking at 05:34 UT today) occurred in the active region just behind the east solar limb. More C-class flares are expected from this active region. The C1.3 flare was associated with a partial halo CME (angular width around 150 degrees). It is a far side limb event, so it will not arrive at the Earth and will have no geomagnetic consequences. The Earth is currently inside a slow solar wind flow following the passage through the ICME on March 31 - April 1. The interplanetary magnetic field magnitude is still elevated (around 7-8 nT), but a relatively low solar wind speed (around 450 km/s) makes sure that the geomagnetic situation will most probably remain on the quiet to unsettled level in the coming hours. Later today we expect the arrival of a fast flow from a trans-equatorial coronal hole that reached the solar central meridian late on March 30, possibly resulting in a geomagnetic disturbance up to the minor storm level (K = 5).
