INFO FROM SIDC - RWC BELGIUM 2013 Dec 05 12:59:57 NOAA AR 1913 which is ready to rotate behind the west limb released yesterday December 4 a C-flare. It is still active but its influence will fade away as soon as its coronal loops disappear behind the limb. NOAA AR 1916 released today, December 5 already a C-flare. A new region at the east limb flared also in the C-level. We expect the C-flaring activity to continue with a probability of 80%, we estimate the chances for an M-flare to be 30%, the chances for an X-flare are small. Earth is in a slow solar wind: around 350 km/s. The magnetic field strength is around 5 nT. The geomagnetic conditions are quiet and are expected to stay so. The coronal hole located just above the solar equator can become geoeffective from December 7. Unsettled to active geomagnetic conditions (K<=4) are possible. |
