Bulletin

Over the past 24 hours, solar flaring activity has been very low, no C-class flares observed. There are four active regions visible on the disk, NOAA AR 3023 with alpha magnetic field configuration and NOAA ARs 3024 (evolved from alpha to beta), 3026 and 3027 are larger and slightly more complex (beta magnetic field configuration). C-class flares are possible in the next 24 hours.

No Earth directed CMEs were detected in the past 24 hours.

The greater than 10 MeV proton flux was at nominal levels and is expected to remain so in the next 24 hours. The greater than 2MeV electron has been slightly above the 1000 pfu threshold over the past 24 hours. It can be expected to decrease in the next 24 hours. The 24h electron fluence is at moderate levels, and is expected to remain so in the next 24 hours.

The solar wind arriving to the Earth is slow, with speeds around 280 km/s and interplanetary magnetic field around 4 nT. The CME that erupted on 2 June is expected to arrive to the Earth early on 5 June, and create disturbed conditions.

Over the past 24 hours, geomagnetic conditions were quiet to unsettled (Kp=1, K_BEL=3). Over the next 24 hours, quiet conditions will be observed until the arrival of the ICME mentioned above, up to minor storm periods can be expected then.

Today's estimated international sunspot number (ISN): 070, based on 20 stations.
