Forecaster summary - Issued 2019-05-04T00:28:40

The high energy electron flux diurnally peaked at high levels on the 3rd May. This diurnal oscillation between Moderate and High levels is likely to repeat itself for the next few days, but with a declining trend. Corresponding 24 hour integrated electron fluence is currently at Active levels (above 1e9 integrated pfu) and is expected to remain that way on days 1 and 2 (4th and 5th May), with a slight chance of Very Active levels (above 1e9 integrated pfu). Later in the forecast period, most likely day 4 (7th May), fluence levels are likely to gradually drop below the active threshold.
