Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels, with active levels at high latitudes on day one (09 April). Quiet to unsettled levels are expected, with isolated active levels at mid latitudes and minor storm levels at high latitudes, on days two and three (10-11 April). The increase in activity is due to a coronal hole high-speed stream.
