Forecaster summary - Issued 2019-08-31T00:18:54

By late on day 1 (31st Aug), once the high speed stream from coronal hole 58 becomes established, an increase in electron flux will be seen, rising to moderate levels ahead of a further increase to high levels from 1st Sep. The associated integrated 24 hour fluence is forecast to remain at normal background levels until early on the 2nd Sep or late  on the 1st, at which point the Active threshold is expected to be reached. The fluence is then expected to remain above the Active threshold for the rest of the forecast period with a chance of it reaching the very active threshold on day 3 and 4.
