Régions solaires actives et éruptions solaires

Solar flaring activity over the past 24 hours was at low levels, with several C-class flares recorded. The largest flare was a C9.4-flare, with peak time 19:03 UTC on July 05 associated with an active region over the west limb. There are currently 8 numbered active regions on the visible disk. NOAA AR 3738 (beta-gamma) and NOAA AR 3733 (beta) were the largest and most magnetically complex regions on disk. Most of the flaring activity in the last 24 hours came from NOAA AR 3729 (alfa) and active regions beyond the west limb. NOAA AR 3737 and NOAA AR 3727 have started to rotate over the west limb. The solar flaring activity is likely to be at moderate levels over the coming days with C-class flares expected and M-class flares likely.

Éjection de masse coronale

No Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images.

Vent solaire

Slow solar wind conditions were recorded over the past 24 hours. The solar wind speed varied within 330 – 380 km/s. The interplanetary magnetic field varied between 2 nT and 9 nT, with the Bz reaching a minimum value of -6 nT. The phi-angle was mainly in the positive sector (directed away from the Sun) with periods in the negative sector. Slow solar wind conditions are expected in the next 24 hours.

Géomagnétisme

Geomagnetic conditions were globally and locally quiet to unsettled (Kp 1-3 and K_Bel 1-3). Quiet to unsettled conditions are expected in the next 24 hours.

Niveaux de flux de protons

Over the past 24 hours the greater than 10 MeV GOES proton flux was at background levels and is expected to remain so over the next days.

Flux d'électrons sur l'orbite géostationnaire

The greater than 2 MeV electron flux measured by GOES 16 was below the 1000 pfu threshold and is expected to remain so in the upcoming days. The 24h electron fluence was at nominal level and is expected to remain so in the next days.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 121, sur la base de 08 stations.
