The Sun Online and solar activity. January 22, 2014

A partial halo CME was detected by SOHO/LASCO on January 21. The CME first appeared in the LASCO C2 field of view at 21:17 UT. It had angular width of around 230 degrees and the speed around 900 km/s. Inspection of STEREO/EUVI B data indicates that the CME was associated with a far side eruption (as seen from the Earth) starting around 21:06 UT, with the source region situated around S15W150. This CME will therefore not arrive at the Earth and have no geomagnetic consequences.
