Geophysical Activity Forecast: The geomagnetic field is expected to be unsettled to active with a chance for a minor storm on day 1 (2 February) due to coronal hole effects along with intermittent periods of Bz south. On day 2 (3 February), unsettled to active conditions are forecast until the anticipated mid-day arrival of the CME from 30 January, when an isolated minor storm will become likely. Conditions on day 3 (4 February) are expected to be mostly unsettled to active as coronal hole effects begin to wane.
