    Geophysical Activity Forecast: Geomagnetic field activity is expected to be at quiet to unsettled levels during days 1 - 2 (05 - 06 September) with a chance for active levels. This is due to the arrival of CMEs observed on 02 September along with a co-rotating interaction region in advance of a coronal hole high-speed stream (CH HSS). The CMEs are expected to arrive around midday on day 1. The CH HSS is expected to commence on day 2. Field activity is expected to be at quiet to unsettled levels on day 3 (07 September) as CH HSS effects subside.
