Solar activity was dominated by an M6.5 flare from NOAA AR 2027 peaking at 14:05 UT, April 2. It was associated with a filament eruption and type II radio bursts. The corresponding full halo CME was first visible in LASCO C2 at 13:36 UT. Measured projected speeds by CACTus vary between 500 km/s and over 1500 km/s. The bulk of the mass was expelled in north east direction. Given the location of the source region and the direction of the ejecta the impact on earth will probably be limited. We can expect at least the impact of the CME driven shock but also a weak impact of the CME itself is probable. Arrival is likely to be around midnight April 4 to 5. Solar wind speed decreased rather steadily from just above 400 km/s to now just above 360 km/s. The total magnetic field was stable in the 4 to 6 nT range. No signatures of the anticipated arrival of the CMEs of March 28, 29, and 30 have been observed. Geomagnetic conditions were at quiet levels (both local K and planetary Kp <=2) over the last 24 hours. Geomagnetic conditions are expected to remain quiet in the next 36 hours. Afterwards, the arrival of the April 1 and April 2 CMEs may cause unsettled to active conditions and possibly minor storms. Also the low latitude coronal hole that passed the central meridian late April 1, early April 2 may become geoeffective by midnight April 4 to 5.
