公告

Over the past 24 hours the level of the solar flaring activity increased. A total of 19 flares were reported, 5 of them were M-class flares and 14 were C-class flares. Most of the flaring activity originated from NOAA AR 3213, which still has a beta-gamma photospheric magnetic field configuration and it produced the strongest reported flare, an M6.4 class flare which peaked at 23:04UT on February 07. Other sunspot groups observed on the visible side of the solar disk still have an alpha or beta photospheric magnetic field configuration. We expect solar flaring activity to stay at similar levels, with C-class flares expected and with a possibility of M-class flares.

During the last 24 hours there were no potentially Earth-directed coronal mass ejections 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 and is expected to remain so. The 24h electron fluence was at nominal levels and is expected to remain so over the next 24 hours.

Earth is still inside the fast solar wind, with a solar wind speed of about 530 km/s. The interplanetary magnetic field magnitude ranged from 6-9 nT. We expect these conditions to persist for the next 24 hours.

During the last 24 hours, the geomagnetic conditions were unsettled (K-Bel=2-3 NOAA-Kp=3). Geomagnetic conditions are expected to be quiet to unsettled in the next days.
