G0KYA's HF Propagation Prediction Report: Recent Episodes
Steve Nichols G0KYA
A regular look at solar conditions and how these affect shortwave propagation on the HF bands. Looks at what you are likely to be able to work on the amateur bands and when.
Have we seen the peak of solar cycle 24? Is the best yet to come? And how are HF conditions going to be this autumn.
Have we seen the solar cycle peak or is there more to come? What about visible aurora? Also do you really need lots of sunspots to work DX on 10m - perhaps not.
The solar flux is hitting new record highs for this cycle and the upper HF bands are humming. Find out what you are missing on 10m alone, plus a guide to all the other bands for this winter.
What are solar flares? What effects do they have on the HF bands and how can you tell if we have had one using satellite data?
What have the last 30 days been like, and what's the connection between solar flux, sunspot numbers and solar flares?
The solar conditions for the past month, plus what you can expect to work on each band.
A look at the state of the current solar cycle, NASA's new predictions and a band-by-band breakdown of what you can work and when.
A change to the normal format. This month we feature an interview with solar physicist Dr Lucie Green and another with Carl Luetzelschwab K9LA about Top Band propagation
