Solar flaring activity was restricted to a single B2 event at the start of the period. NOAA 2526 remained quiet. No earth-directed coronal mass ejections (CMEs) were observed. The x-ray background flux was steady at the A7 level.

Quiet conditions are expected to continue.

The Kp index reached minor storming levels on 2 April during the 15-18UT interval, and moderate geomagnetic storming during the 21-24UT interval. K Dourbes was resp. at minor storming and active conditions. This geomagnetic activity was the result of the arrival of a co-rotating interaction region and associated wind stream from a negative coronal hole.

Solar wind speeds continued to gradually increase from about 330 km/s at 08:00UT to about 530 km/s around 21:30UT. A sharp drop in wind density from 40 to 7 particles per cm3 occurred at 14:05UT, coinciding with a final shift in the direction of the interplanetary magnetic field from away to towards the Sun. It was followed about an hour later by a strong dive of Bz towards negative values around -14 nT, with sustained but gradually weakening negative values over the subsequent 7 hours.

Currently, wind speed is declining with values near 400 km/s, and Bz varying between -5 and +5 nT. Mostly unsettled to active geomagnetic conditions are expected for the rest of the day (3 April), a minor storming episode not excluded. The wind stream from an elongated negative coronal hole between latitudes +10 and +30 degrees is still expected to influence the earth environment starting from 4 April onwards.
