Solar Active Regions and flaring

Solar flaring activity was moderate over the past 24 hours. The largest flare was a M6.1-flare, with peak time 15:25 UTC on June 06, from NOAA AR 3697 (beta-gamma-delta). There are currently 9 numbered active regions on the visible disk. NOAA AR 3697 is the most complex AR (beta-gamma-delta) and responsible for the majority of the flaring activity. 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.

Coronal mass ejections

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

Solar wind

The solar wind at the Earth was slow, with speeds up to 400 km/s and interplanetary magnetic field around 7nT and Bz reaching minimum value of -6nT. The possible arrival of high-speed stream from the coronal hole that crossed the central meridian late June 04 is expected on June 08.

Geomagnetism

Geomagnetic conditions were quiet to unsettled both globally and locally (NOAA Kp 3-, Local K Bel 3). Geomagnetic conditions may reach active levels on June 08 due to a high speed stream arrival.

Proton flux levels

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.

Electron fluxes at geostationary orbit

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.

Today's estimated international sunspot number (ISN): 159, based on 21 stations.
