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 […]
Propagation News – 4 February 2018
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 […]

News last week that the Republic of Kosovo (Z6) has been added to the DXCC list of current entities meant that QSOs with the new prefix were in demand. With Z60A on the air from Pristina until 4 February, there has been a sudden interest in propagation paths to the country! VOACAP Online shows that […]

Last week saw unsettled HF conditions in the first half, but more settled ones later on. A high-speed stream from a coronal hole pushed the K-index to four and five last weekend, and maximum usable frequencies were depressed until at least Thursday. The HF bands were often very lacklustre, with even 20m struggling to show […]

Last week, we continued to suffer the effects of coronal holes on the Sun, which are very prevalent at this point in the solar cycle. On Wednesday, HF was very lacklustre with little on the bands and 20m closing around 4pm. Having said that, there were pearls to be found. The 6O6O DXpedition to Somalia […]
