28th – 30th August

Active to minor storm (NOAA Scale G1) conditions are expected with a decreasing chance for a major geomagnetic storm (NOAA Scale G2) for day one (28 Aug) in response to the effects from the pair of CMEs currently affecting Earth. By day two (29 Aug) unsettled to active conditions are expected from a small positive polarity CH/HSS. Quiet to unsettled conditions are forecast for day three (30 Aug) as the CH/HSS impacts subside.
