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 […]
Propagation News – 20 January 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 […]
Propagation News – 13 January 2019
This week saw relatively-settled HF conditions after the effects of a geomagnetic storm that impacted Earth at the weekend had passed. The Kp index was mostly around one or two thanks to a reduced solar wind. A small solar coronal hole did become Earth-facing on Wednesday, the 9th, but its effects, if any, won’t be […]

A new sunspot appeared this week, although it belongs to outgoing cycle 24 and is therefore not a sign that the new cycle 25 is under way just yet. We may still have to wait until at least the autumn before that happens. Despite pushing the solar flux index up to 75 on Thursday we […]

As this report has to take you up until Sunday, 6 January 2019 we can’t guarantee complete accuracy, but we’ll try to predict conditions for the Christmas period. The solar flux index is pretty easy as it looks like it will remain at or near sunspot minimum-like conditions. The SFI will be in the range […]
Propagation News – 16 December 2018
As we are approaching Christmas we have a festive twist to the HF propagation report this week. Firstly though, this week saw a lack of sunspots with the solar flux index around 70. Geomagnetic conditions were better than they have been though due to lack of coronal holes, with the K-index being two, one or […]
