Régions solaires actives et éruptions solaires

Solar flaring activity was moderate over the past 24 hours. The largest flare was a M3.2-flare, with peak time 11.55 UTC on 3 June associated with NOAA AR 3697 (beta-gamma-delta). There are currently 8 numbered active regions on the visible disk. NOAA AR 3697 is the most complex AR and responsible for almost all the flaring activity of the last 24h. The solar flaring activity is expected to be at moderate levels over the coming day with C-class flares expected and M-class flares likely and a chance of X-class flares.

Éjection de masse coronale

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

Vent solaire

The solar wind (sw) at the Earth is slow, with speeds around 300 km/s and interplanetary magnetic field around 5 nT and Bz reaching minimum value of -5 nT. A minor increase of the sw speed and magnetic field is expected in the second half of June 04, due to the potential arrival of the partial halo CME of June 01.

Géomagnétisme

Geomagnetic conditions were quiet to unsettled (NOAA Kp 2, Local K Bel 3). Geomagnetic conditions are expected to be mostly at quiet to unsettled levels in the next 24 hours, however isolated active to minor storm conditions may be possible on June 04, due to the potential arrival from the June 01 CME.

Niveaux de flux de protons

Over the past 24 hours, the greater than 10 MeV GOES proton flux remained below the 10 pfu threshold and is expected to remain so over the next day. There is a slight chance that the proton flux may increase due to strong flaring from NOAA AR 3697.

Flux d'électrons sur l'orbite géostationnaire

The greater than 2 MeV electron flux remained below the 1000 pfu alert threshold, and is expected to remain below the threshold during the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain so.
