Propagation Update – January 19, 2018

Propagation Forecast Bulletin 3  ARLP003 From Tad Cook, K7RA Seattle, WA  January 19, 2018 To all radio amateurs It was a quiet week in space weather (January 11-17) with 0 sunspots over the weekend and geomagnetic indicators rising only slightly. Compared to last week, average daily sunspot numbers declined from 11.9 to 7, but average daily solar flux went from 69.9 to 70.7. Seems counter-intuitive that sunspot and solar flux would move in opposite directions, but these are all very low numbers anyway, and any change is slight. Also, there…

Propagation de K7RA

From Tad Cook, K7RA Seattle, WA November 18, 2016 To all radio amateurs  Solar flux and sunspot numbers moved in opposite directions over the past week, and differences were more extreme than usual. Normally we expect daily sunspot numbers and solar flux to track together, and geomagnetic indices to track with each other as well, at least approximately. Average daily sunspot numbers over the past reporting week (November 10-16) rose 10 points from 18.7 to 28.7, while average daily solar flux dropped from 76.9 to 45.8. These comparisons express differences…
