The high energy electron flux varied diurnally between background and moderate levels. This is likely to remain the case, perhaps dropping to mostly background levels, until day 3 and 4 (9th-10th Dec) when Earth may connect with a High Speed Stream from CH01/-. This HSS may increase the electron count above the 1000pfu threshold, especially near the diurnal maximum.

Corresponding 24-hour integrated electron fluence values are expected to remain below the Active threshold (1e8 integrated pfu), with an increase possible on day 3 and 4 in association with the possible increase in solar wind speeds from CH01/-, this would lead to a slight chance of the 1e8 integrated pfu threshold being exceeded on these days.
