Bulletin

Solar X-ray flux remained below C level throughout the period. NOAA region 2764 (responsible for the M1 flare on May ) had been numbered at the start of the period due to the presence of a single polarity spot, but it has meanwhile already decayed into plage. A new region still behind the South East limb appears to be active and may increase flaring probabilities in the next days. Overall the probability for C class flares remains low currently.

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 continued to decline from just under 400 km/s to around 330 km/s currently. The total magnetic field increased yesterday afternoon and remained between 5-7.5nT since then, with a consistent negative Bz component of around -5nT. The magnetic field phi angle switched briefly into the negative sector during yesterdays afternoon. Solar wind is expected to remain near nominal over the next days.

Geomagnetic conditions were quiet to unsettled (both NOAA Kp and local K 1-3). Quiet to unsettled conditions are expected over the next days.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 000, sur la base de 28 stations.
