Bülletään

Over the past 24 hours, the solar flaring activity has been at low levels with a total of 8 low level C-class flares. Most of the flaring activity originated from the NOAA AR3281, which recently rotated onto the visible side of the solar disk. A total of 8 numbered active regions are presently observed on the visible side of the solar disk, all with a simple configuration of their photospheric magnetic field (alpha or beta). For the next 24 hours, we expect C-class flares and possibly isolated M-class flares.

During the last 24 hours there were no potentially Earth-directed coronal mass ejections (CMEs) detected in the available coronagraph observations.

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours. The greater than 2 MeV electron flux has been below the 1000 pfu threshold. It is possible that an increase is observed over the coming days. The 24h electron fluence was at normal levels and is expected to stay below the threshold over the next 24 hours.

Over the past 24 hours, the solar wind speed was between values of 350 km/s and 400km/s, while the interplanetary magnetic field strength was about 6 nT. For the coming days, we expect Earth to be under minor influences of the solar wind originating from the two positive polarity coronal holes which crossed the central meridian over the past days.

During the last 24 hours the geomagnetic conditions were quiet and we expect quiet to unsettled geomagnetic conditions in the coming hours.
