Propagation News – 15 October 2023
We had a period of low geomagnetic disturbance last week, which allowed the upper HF bands to shine. There were lots of reports of DX being worked on the 10m band as the Kp Index sat mainly in the ones and twos, with a maximum of Kp 3.33 for one three-hour period on the 9 […]
Propagation News – 8 October 2023
Last week progressed quite well from a solar point of view, at least until the morning of Thursday 5 October when the Kp index rose to five. But the Kp high was short-lived and only lasted for one three-hour reporting period. Until this point, it had been around one to three all week, which meant […]

Another week of disrupted solar and geomagnetic conditions saw the Kp index go up and MUFs come down. A period of minor G1 geomagnetic storming was observed on Tuesday the 26 September thanks to an enhanced solar wind stream containing a long-duration southward-facing Bz component. If the solar wind’s Bz magnetic field points south, it […]

Last week’s space weather was very disturbed from a geomagnetic point of view. The Kp index hit 6.67 on the 19 September, spawning reports of visible aurora from around the UK once again. This was the result of a coronal mass ejection passing Earth, which caused a period of strong G3 storming very early that […]

While our terrestrial weather this week was variable, it seems our space weather was equally unsettled! We warned last week that it wouldn’t take much to cause the Kp index to rise and on Tuesday a coronal mass ejection, or CME, hit the Earth sending the Kp index to 5.67. The Bz component of the […]
Propagation News – 10 September 2023
The propagation team was caught out last week by two coronal mass ejections, or CMEs, that came off the edge of the Sun. The arrival of those CMEs on the 3 September eventually pushed the Kp index to 5.67. In its report, Spaceweather.com said that it was possible that a CME arrived on the 2 […]
