The solar flaring activity was at low level with several C-class flares being detected in the last 24 hours. The largest flare was a C2.7 flare, peaking at 05:30 UT, associated with region NOAA AR 3158, that emerged yesterday in the northern hemisphere. As there are no complex active regions observed on the visible side of the solar disk, solar flaring activity is expected to be at low levels, with C-class flares likely and a chance for M-class flares.
During last 24 hours there were no potentially Earth-directed CMEs detected in the available coronagraph observations.
In the past 24 hours the greater than 10 MeV proton flux remained at the background levels. The greater than 2 MeV electron flux exceeded the 1000 pfu threshold during the last 24 hours. The electron flux is expected to continue to exceed this threshold over the next day. The 24h electron fluence was at moderate levels. The electron fluence is expected to be at moderate to high levels in the next 24 hours. The solar wind speed has decreased, and it is presently about 520 km/s. The interplanetary magnetic field magnitude is about 5 nT. The magnetic field orientation was predominantly in the positive sector (field directed away from the Sun). A large trans-equatorial negative polarity coronal hole is crossing the central meridian. The solar wind originating from this equatorial coronal hole is expected at Earth from Dec 07.
During last 24 hours the geomagnetic conditions reached active levels levels (NOAA KP 2-4 and Local K Dourbes 2-4). Geomagnetic conditions are expected to be at unsettled levels during next hours.
Today's estimated international sunspot number (ISN): 115, based on 03 stations.
