Bulletin

Solar X-ray flux remained below C level throughout the period. NOAA region 2765 is fairly simple but showed some flux emergence and spot formation near the main spot, and produced a minor B3.5 flare just after midnight 00:01UT The overall probability for C flaring remains 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.

Solar wind speed increased to within the 310-350 km/s range while total magnetic field remained at or below 5nT with a variable Bz component. The magnetic field phi angle switched between the positive and negative sector a couple of times. Near nominal Solar wind conditions are expected over the next 24 hours, but are likely to become slightly enhanced on June 6 associated to some faint on disc coronal hole signatures.

Geomagnetic conditions were quiet to unsettled (NOAA Kp 0-2 and local K Dourbes 0-3). Quiet to unsettled geomagnetic conditions are expected over the next 24 hours, later from June 6 increasing to unsettled and possibly active conditions.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 011, sur la base de 17 stations.
