The solar flaring activity was at low levels with few C-class flares. The flaring activity over the next 24 hours is expected to remain at low levels with some C-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; due to the solar wind conditions it is expected to increase and coss the 1000 pfu threshold over the next 24 hours. The electron fluence was at normal to low levels and it is also expected to increase to more eleveted levels over the next 24 hours.

Earth is currently under the influence of the fast solar wind conditions. The solar wind parameters are enhanced due to the arrival of the high-speed stream associated to the equatorial coronal holes (positive polarity) reaching to the central meridian of the Sun on December 20. The solar wind speed reached values of 600 - 650 km/s, the total interplanetary magnetic field remained slightly enhanced and reached values up to 11.0 nT with the southward interplanetary magnetic component, Bz, ranging between -9.7 nT and 7.8 nT. The solar wind enhancement is expected to persist for the next 24-hour periods.

During the last 24 hours, the geomagnetic conditions were active with some periods of minor storms (NOAA-Kp=5, and K-BEL=5) in response to the enhanced solar wind condition. Geomagnetic conditions are expected to remain mostly active with possible minor short duration minor storm in the next days.
