⛭⛣⚴⛭∇⛣♆.⚴☋☿☿☿ 31 May CME

 There was a big M8 flare earlier in the day, a long duration one that resulted in a fast moving CME, that is forecasted to cannibalise two previous CMEs on the way to the Earth tomorrow, striking around 5:30 UTC. It will only be a glancing blow though. Detailed forecasts are awaited, UK Weather Services are saying G4.
