Solar flaring was limited to B flares, originating in the afternoon from NOAA region 2659 as it rotated behind the limb, and this morning from a new region rotating on disk in the East. Further B flaring may be expected from this new region, and also C flaring could be possible but proper region analysis of the new region is currently not yet possible. From around 20:48UT, SoHO/LASCO C2 coronagraph images show the CME associated to the filament eruption that was reported yesterday. The coronagraph images indicate that the CME is directed Eastward and has a limited angular extent of less than 90 degrees. No influence on Earth is expected. No other CMEs were visible in coronagraph images. Proton flux levels were at background values and expected to remain so.

Solar wind conditions were slightly enhanced but stable. Solar wind speed was in the 470-540 km/s range and total magnetic field was in the 5-8nT range with Bz variable. The magnetic field phi angle indicated a positive sector throughout the period. Solar wind conditions are expected to enhance later in the period with a possible high speed stream influence of the equatorial coronal hole that transited the central meridian late May 29. Geomagnetic conditions were quiet throughout the period (both local K Dourbes and NOAA Kp 0-2). Unsettled to active conditions could arise from the influence of the equatorial coronal hole later in the next 24-48 hours.
