Forecaster summary - Issued 2019-09-27T00:25:46

Initially little change is expected in electron flux counts today, with the flux remaining at background to moderate levels. However, once the high speed stream from CH65/+ becomes established a marked increase in the flux is expected, reaching high or very high levels from 28 Sep onwards. The fluence is expected to rapidly increase as well through tomorrow, reaching Active levels by the end of the day. Thereafter confidence is high that that fluence will remain above the Active threshold, and is likely to reach Very Active by the end of day 4 (30th). This would follow a similar pattern which occurred during the previous rotation.
