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 and 3024 remain stable and simple (alpha magnetic field configuration). NOAA ARs 3026 and 3027 are larger and slightly more complex (beta magnetic field configuration). These regions could produce C-class flares 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. Since the high speed solar wind stream is not affecting the Earth anymore, it can be expected to decrease. 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 330 km/s and interplanetary magnetic field around 4 nT. Similar conditions are expected for the next 24 hours.

Over the past 24 hours, geomagnetic conditions were quiet to unsettled (Kp=2, K_BEL=3). Over the next 24 hours, similar conditions are expected.

Today's estimated international sunspot number (ISN): 058, based on 21 stations.
