Solar flare activity was very low over the last 24 hours. The strongest event was a B4-flare peaking at 18:19UT on 29 May, produced by NOAA 2073. There are currently 5 sunspot groups visible. They are all small and magnetically simple, including the two new groups Catania 65 (near east limb) and Catania 59. The active region on the Sun's farside continues to produce quite strong CMEs (e.g. 29 May at 09:24UT) and is expected to round the east-northeast limb tomorrow. Flaring activity is expected to be low, with a chance on a C-class flare. Solar wind speed first declined from 380 to 310 km/s around midnight, then gradually increased again to 360 km/s. Bz varied between -7 and +6 nT. The geomagnetic field was quiet with locally some K=3 episodes. A small coronal hole that passed the central meridian on 25-26 May can still influence the geomagnetic field later today. Geomagnetic conditions are expected to remain quiet, though locally a brief active episode is possible.
