The solar flaring activity was at low levels with several C-class flares. The larger flare was a C6.8-class from the sunspot region, NOAA-AR 3169 (with a beta-gamma magnetic complexity) peaking at 22:36 UTC on December 22. The flaring activity over the next 24 hours is expected to remain mostly at low levels, with C-class flares expected and a small possibility for M-class flares.

Several coronal mass ejections and flows were observed in the currently available SOHO/LASCO coronagraph imagery and automatically detected by the Cactus tool over the past 24 hours. However, no clear Earth-directed coronal mass ejections were identified.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours and is expected to remain so in the next 24 hours. The greater than 2 MeV electron flux was below the 1000 pfu threshold over the past 24 hours and is expected to remain below the 1000 pfu threshold over the next 24 hours. The electron fluence was at normal to low levels and is expected to stay at normal levels over the next 24 hours.

The solar wind parameters were slightly enhanced. The solar wind speed remained slow around 340-440 km/s, the total interplanetary magnetic field remained slightly enhanced and reached values up to 13.1 nT with the southward interplanetary magnetic component, Bz, ranging between -10.2 nT and 11.7 nT. The high-speed stream associated to the equatorial narrow coronal holes (positive polarity) facing Earth Earth yesterday may enhance the solar wind measurement near Earth in about two days from now.

During the last 24 hours, the geomagnetic conditions were mostly quiet with some periods of untested condition (NOAA-Kp=1-3, and K-BEL=1-3). Geomagnetic conditions are expected to remain quiet with periods of unsettled conditions in the next days.
