Forecaster summary - Issued 2018-05-05T00:00:28

The high energy electron flux (greater than 2MeV) is expected to remain below the Active threshold, but may rise above on Day 3 or 4 as a typical delayed response to the forecast high speed stream on Day 2. The corresponding fluence may rise above the Active threshold later Day 3 or Day 4. The flux from the previous rotation suggests a possible rise on Day 4 (8th May), but the forecast may be slightly advanced on this rotation. Evidence for this comes from the passage of coronal hole 93 past Stereo A, but there is still relatively low confidence regarding the timing.
