We just completed a second full week of no visible sunspots. Average solar flux was about the same as the previous week, and was below the average for the past 90 day average, which is 71. It looks like conditions related to the next cycle are not about to turn up yet.
Over the month of October solar flux is expected to hover around 70 or below, as solar activity continues to stay very low. The geomagnetic field is expected to become unsettled to active due to recurring coronal holes from October 7-9, 17-20 and 23-25.
Sunspot Numbers for September 26 through October 2 were 0, 0, 0, 0, 0, 0 and 0, with a mean of 0. 10.7 cm flux was 70, 69.8, 71, 70.1, 69.5, 69.5 and 69.7, with a mean of 69.9.
