Bulletin

Solar X-ray flux remained below C level throughout the period. NOAA region 2764 in the northern hemisphere decayed to plage and is inactive. The region turning onto the disk in the South is awaiting analysis and is yet unnumbered, but appears to be relatively inactive presently. The overall probability for C flaring is low.

There were no Earth directed Coronal Mass Ejections (CMEs) observed in coronagraph data.

The greater than 10 MeV proton flux levels were at background values and are expected to continue to be at background level. The greater than 2 MeV electron flux has been nominal over the past days.

There is a low latitude extension of the northern polar coronal hole visible that may influence Solar wind conditions starting around late June 6.

Solar wind conditions were nominal, with Solar wind speed in the 320-360 km/s range. Total magnetic field was around and mostly below 5 nT with a variable Bz component. The magnetic field phi angle was mostly in the negative sector with some excursions into the positive sector. Solar wind conditions are expected to be near nominal over the next days, with later an expected sector boundary crossing and possible enhanced conditions by late June 6.

Geomagnetic conditions were quiet (local K Dourbes 0-2 and NOAA Kp 1-2). Quiet to unsettled geomagnetic conditions are expected in the next days.

Today's estimated international sunspot number (ISN): 010, based on 21 stations.
