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.

Solar Activity Forecast: Solar activity is expected to be low to moderate with a slight chance for a major event for the next three days (03-05 August). Region 1261 and Region 1263 are both capable of producing a major event and both have a slight chance of producing an energetic proton event.

Geophysical Activity Forecast: The geomagnetic field is expected to be quiet on day one (03 August). Day two is expected to be predominately quiet with chance a for isolated active conditions late in the day. Day three (05 August) is expected to be unsettled to active with a chance for minor storm conditions. The increase in activity is forecast due to the expected arrival of the coronal mass ejection from 02/0616Z. Due to the enhanced environment there is a chance for the 10 MeV protons to cross event thresholds with shock arrival.

Geomagnetic Forecast: The geomagnetic field isexpected to be at minor to major storm levels with a chance for severe storm periods as the effects of three CMEs are expected toimpact the Earths geomagnetic field early on 05 August. Active tominor storm levels are expected on 06 August. Unsettled to activelevels are expected on 07 August.

CME has arrived, high and mid latitudes on red alert with low lats on amber-anyone with clear and dark skies should look out for aurora now
