Propagation News – 27 January 2019

This week we did get a new sunspot group, which pushed the solar flux index to 71 and the sunspot number to 18, reflecting one group with eight spots in it. But, as predicted last week, incoming matter from a solar coronal hole resulted in an elevated K-index and poor HF conditions on Wednesday, the 23rd. Because of this, maximum …

The K7RA Solar Update

RSGB January 18, 2019 At the risk of sounding like a stuck record, the Sun remained spotless this past week with a solar flux index stuck firmly around the 70 mark. Geomagnetic conditions were mostly settled with a maximum planetary K-index of four, although on average it was usually much lower than this, around one or two. Many are bemoaning …
