Forecaster summary - Issued 2018-05-04T00:21:28

With solar winds near ambient levels today and tomorrow (4th and 5th May)  there is not expected to be any mechanism to increase electron counts, therefore the flux will remain within moderate levels. However, during day 3 (6th May) a fast solar wind from coronal hole 93 is expected to become geoeffective, resulting in electrons exceeding the High (1000 pfu) threshold from possibly late day 3 but most likely during day 4 (7th).  The corresponding electron fluence is expected to remain below the High threshold throughout the four-day period, albeit with a rising trend through day 4 (7th May).
