NOAA 2071 produced the only flare of the period, a C1 flare peaking at 04:30UT this morning. The 4 sunspot regions currently visible are all small and magnetically simple. No Earth-directed CMEs were observed. An active region on the Sun's farside that produced several substantial CMEs over the past few days, is expected to round the east limb within 2 days. Flaring activity is expected to be low, with a small chance on a C-class flare. For most of the period, solar wind speed was stable around 330 km/s, with Bz varying between +6 and -5 nT. Around 08:30UT, a shock was observed in the ACE-data. Solar wind speed jumped from 330 to 380 km/s, and Bz from -5 to -8nT. The geomagnetic field was quiet, with the K index reaching 3. A small coronal hole that passed the central meridian on 25-26 May could influence the geomagnetic field starting late on 29 May. Geomagnetic conditions are expected to remain quiet, though locally a brief active episode is possible.
Today's estimated international sunspot number (ISN): 035, based on 15 stations.
