Bulletin

Solar flaring activity was at moderate levels over the past 24 hours with several C-class flares and a few low-level M-Class flares detected. NOAA Active Region 3056 was most active and produced an M1.3 and an M1.1 flare peaking at 23:43UT and 09:19UT, respectively. The flaring activity is expected to be at moderate levels with C-class flares expected, M-class flares are probable and a slight chance for an X-class flare.

No Earth directed Coronal Mass Ejections (CMEs) have been observed in the available coronagraph data.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours and is expected to remain so in the next 24 hours. The greater than 2MeV electron flux was below the 1000 pfu threshold and is expected to remain so over the next 24 hours. The 24h electron fluence was at normal levels and is expected to be at normal levels over the next 24 hours.

The solar wind speed ranged between 315 and 410 km/s. The total magnetic field ranged between 5 and 10 nT. The interplanetary magnetic field phi angle was predominantly in the positive sector (directed away from the Sun). The solar wind conditions are expected to become enhanced from July 12 due to a combination of the arrival of the solar wind associated with the positive polarity coronal hole, which began to cross the central meridian on July 09, and a possible glancing blow from the CME observed on July 8.

Geomagnetic conditions were quiet to unsettled over the past 24 hours (NOAA Kp 1-3 and Local K-Dourbes 0-3). Geomagnetic conditions are expected to be mostly quiet on July 11, with active to minor storm conditions possible from July 12.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 131, sur la base de 21 stations.
