Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (13 November). Activity is expected to increase to mostly unsettled levels on day two (14 November) and unsettled to active levels on day three (15 November). This increase in activity is due to the arrival of multiple small CME's mixed with the effects of a recurrent coronal hole high-speed stream.
