Solar activity was very low, with X-ray flux remaining below B level. A new region is rotating onto the disk, but at present chances for C flares are still judged to be very low.
No Earth directed CMEs have been observed in coronagraph data.
Proton flux levels were at background values and are expected to remain so.
A small negative polarity coronal hole in the southern hemisphere has passed the central meridian yesterday. It may become geoeffective from late June 12.
Solar wind conditions have been nominal with solar wind speed further decreasing to below 300 km/s. Total magnetic field was 1-4 nT with the Bz component mainly negative but not reaching below -3nT. The magnetic field phi angle was initially variable but now clearly indicates a negative sector connection. Solar wind conditions may become slightly disturbed from late June 12 due a small coronal hole in the Southern hemisphere.
Geomagnetic conditions were quiet (local K Dourbes 1-2, and NOAA Kp 1) and are initially expected to remain so. Later unsettled conditions may be experienced.
Today's estimated international sunspot number (ISN): 000, based on 14 stations.
