The geomagnetic field is expected to be predominately quiet on day one (February 17). An increase to unsettled to active conditions, with a chance for minor storm periods is expected late on day one into day two (18 February). The increased activity is forecast due to the expected arrival of the CME associated with the X2 flare that occurred on 15/0156Z. Day three (19 February) is expected to be quiet to active as the disturbance subsides.
