Solar Active Regions and flaring

There are ten visible active regions on the solar disk. NOAA AR 3315 remains the most complex region, again with beta-gamma-delta magnetic field configuration. It produced the largest flare of the past 24 hours, M1.4 peaking at 13:38 UTC on 30 May. Nevertheless, an active region rotating into view from the east limb is also producing M-class flares and elevating the x-ray background levels. More M-class flares can be expected and X-class flares are possible.

Krooniaine massiline väljavool

No Earth-directed coronal mass ejections (CMEs) were detected in the available coronagraph imagery.

Krooniauk

A positive polarity coronal hole in the southern hemisphere crossed the central meridian on 29 May. A related high speed solar wind stream may arrive to the Earth on 2 June.

Päikesetuul

The Earth is inside slow solar wind, with an interplanetary magnetic field around 7 nT and solar wind speed of about 380 km/s. Similar conditions are expected for the next 24 hours.

Geomagnetism

The geomagnetic conditions over the past 24 hours were quiet (K_Belgium and Kp below 3). Mostly quiet geomagnetic conditions are expected for the next 24 hours.

Proton flux levels

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

Electron fluxes at geostationary orbit

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

Today's estimated international sunspot number (ISN): 171, based on 19 stations.
