The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet to unsettled with a slight chance for active
conditions on day 1 (16 August) due to effects from the 13 August
CME. Unsettled to active levels with a slight chance for minor storm
conditions are expected on Day 2 (17 August) due to effects from the
14 August CME. Quiet to unsettled levels with a slight chance for
active conditions are expected on Day 3 (18 August) as effects of
