This week has been geomagnetically quiet with the K-index hovering around zero or one. This is in contrast to the extremely unsettled conditions we have been having on and off over the past few months. Coupled with a solar flux index of around 110 to 120 this has brought reasonably settled conditions on HF and […]

This week has been a bit of a mixed bag in terms of HF propagation. The early part of the week saw reasonable openings on 18 and 21MHz, although a continuous K-index of around three due to the high speed solar wind stream, took its toll. The VK9WA Willis Island DXpedition was even audible on […]

We’ve had another week of disrupted HF conditions, thanks to an ongoing high-speed solar wind stream. The K-index hit six on the 10th and five on the 11th showing severe geomagnetic storming. The maximum usable frequency over a 3,000km path has yo-yoed this week, being as low as 19.7MHz at noon on Tuesday, but hitting […]

This week saw a perfect example of how the sun affects HF propagation. As we predicted last week, a high-speed solar wind stream hit the earth on Tuesday. This pushed the K-index to five as the incoming plasma had a south-facing Bz field that enabled it to more easily couple to the Earth’s magnetic field. […]

It has been another week with great HF conditions. Last weekend gave many people the chance to work DX on 10 metres in the CQ Worldwide contest. The solar flux index stayed above 110 and geomagnetic conditions were generally quiet, especially compared with the problems we had with high speed solar wind streams last month. […]

This week has shown just how good the upper HF bands can be. A healthy solar flux index of 120 or more, plus settled geomagnetic conditions, has seen maximum usable frequencies rise to more than 30MHz. As a result, a lot of DX has been heard and worked, especially on 10 and 12m. This weekend […]
