Sun erupted slow-moving Coronal Mass Ejection (CME) on February 19, 2013. Goddard Space Flight Center reported that the bulk of the plasma cloud was directed to the north of Earth. Still, we can expect a glancing blow around February 22, 2013. Minor to moderate geomagnetic disturbances will be possible at very high latitudes backed by aurora displays.   NOAA/SWPC forecasters estimate 55% chances for M-class and 15% chances for X-class solar flare eruptions. The geomagnetic field is expected to be at quiet to active levels on February 20, quiet to unsettled levels on February 21 and quiet levels on February 23, 2013. Protons have...
