COMMENT: Solar flaring activity is low. Feb 10 and today, Feb 11, only B-flares
were seen, coming mostly from sunspot group 57 (NOAA 0554). The solar wind speed
fluctuates between the values of 380 and 360 km/s. On Earth, we experience quiet
geomagnetic conditions. From Feb 12, active conditions with periods of possible
minor storm conditions are expected due to the present coronal hole.
