Propagation News – 6 October 2024
In the first week of October, the 10m band began to show what it is capable of. With a solar flux index in the high 200s and calm geomagnetic conditions, DX was plentiful. Nick, VK9DX on Norfolk Island was audible on SSB all morning on Wednesday 2 October and only wanted to work G stations. […]

Solar activity is back to moderate levels with an M3.7 solar flare detected on 22 September. Newly assigned AR 3835 in the south-east quadrant is the main source, and the event looks to have thrown a stream of plasma into space. The latest model suggested a possible passage near our planet by the 25th and […]
Propagation News – 22 September 2024
It was a topsy-turvy time for HF propagation last week with a declining solar flux index and geomagnetic disturbances thanks to coronal mass ejections (CMEs) from the Sun. The solar flux index declined to the mid-160s, and the Kp index had a couple of excursions to more than 7. These were due to CMEs and […]

Last week showed that HF conditions are improving as we head into the autumn. With a solar flux index still above 200, there was plenty of DX available to work. CDXC members reported working VP6WR on the Pitcairn Islands, KH8T on American Samoa and 3D2USU on Fiji, which is not a bad catch for early […]

Last week was underlined by continued high solar flux indices and excellent 10m band propagation to CY9C on Saint Paul Island near Newfoundland. The DXpedition, which has now ended, was often at S9+ on 28MHz up to two hours after sunset. This may be a sign that better autumnal HF conditions are just around the […]
Propagation News – 1 September 2024
We had a good week for HF propagation, at least until we had a Kp index of 5.67 on Wednesday, the 28th. This was caused by the Bz component of the interplanetary magnetic field moving into a south-pointing position. Luckily, it didn’t last long and geomagnetic conditions were back to normal by Thursday. The solar […]
