A couple of low level B flares were recorded from Catania group 67 (NOAA region 2692) which has become a bipolar region and has shown clear growth and development of its magnetic complexity. Chances for possible C flaring have hence increased but are still low. No Earth directed CMEs have been observed in coronagraph data. Proton flux values are at background levels and are expected to remain so.
Solar wind was nominal with solar wind speed decreasing from near 450 km/s to around 400 km/s and total magnetic field in the 3-4nT range. Solar wind conditions may increase slightly. However, the leading part of the previously elongated coronal hole, that now seems to have become detachedv is not expected to result in any significant high speed stream effects. The more significant high speed stream influence from the trailing part of that previously elongated coronal hole is expected to increase Solar wind conditions from around noon December 23. Geomagnetic conditions were quiet (both local K Dourbes and NOAA Kp 0-2). They are expected to remain at quiet to unsettled levels but increasing towards noon December 23 when active periods and possibly minor storms become possible under the influence of the anticipated high speed stream.
