Quieter geomagnetic conditions helped improve HF propagation this week. At times the K-index was actually zero, thanks to a respite from the continual coronal holes on the Sun that have caused disruption. The solar flux index continued to hover around the high 60s due to a lack of visible sunspots. Despite this there was plenty […]

As we move into March, HF conditions should be well under way to being more spring-like. As the days gets longer and the nights get shorter, the LF and MF bands can become less attractive and the HF bands can show a little more life for a little longer into the evening. March is also […]

Despite warnings in the popular press that a massive solar flare was likely to cause chaos on Earth, we managed to survive! In the event, a coronal mass ejection, which was linked to the solar flare, caused the K-index to rise to five on Monday, the 19th, but conditions became more settled from Tuesday onwards. […]

Sunspot group 2699 threw a surprise last week when it unleashed a C-class solar flare and a coronal mass ejection. While we have got used to having coronal hole activity, CMEs have been less prevalent over the last few months. The CME and a coronal hole solar wind stream were predicted to reach Earth by […]

Sunspot region 2699 provided us with a small increase in solar activity last week. It also produced a number of minor C and M-class flares as the solar flux index rose to around 77. More significantly, quieter geomagnetic conditions, thanks to a lack of coronal holes, meant the K-index remained fairly low and the bands […]

Solar activity remained at very low levels last week, with one barely-visible sunspot group pushing the sunspot number to a maximum of 13 and the solar flux index to 69. Geomagnetic conditions were largely settled, with some coronal hole activity pushing the K-index to three at times. Despite the low SFI, there was band activity […]
