Geophysical Activity Forecast: Geomagnetic field activity is expected to be at unsettled to minor storm levels on day 1 (04 August) as the current CME passage continues. Activity is forecast to increase to active to minor storm levels with a chance for major storm levels on day 2 (05 August) due to the arrival of the halo-CME observed on 01 August (associated with a large filament disappearance). Activity is expected to decrease to unsettled to active levels on day 3 (06 August) as CME effects subside.
