Six sunspot regions are visible at the front side of the solar disk. All have a simple alpha or beta magnetic configuration. The background of the GOES Xray flux is at B-class level and no noteworthy flares were measured. A weak CME erupted towards the north, first visible in LASCO/C2 at 5:36 UT on 28 April. It can hardly be called a partial halo CME and does not seem to be Earth directed. C-class flaring activity can be expected for the next 48 hours. Solar wind speed is relatively stable with values between 300 to 350km/s. The magnitude of the interplanetary magnetic field was maximally 5 nT with a mainly negative Bz. Geomagnetic conditions were unsettled and are expected to remain as such. An isolated time slot of active
conditions is possible at arrival of a high speed stream related to the coronal hole that passed the central meridian early on 24 April.
