Propagation News – 26 March 2023
The solar flux index dipped a little last week, down to 148, but it didn’t last long and was back up to 159 by Thursday 23 March. We were free of major solar flares with only one M-class flare occurring on the 20 March. Geomagnetic conditions were mainly settled as well, but that could change […]

Last week was split in two, in terms of HF propagation. The first half of the week was characterised by excellent high-band conditions, with many people commenting on how good things were. The Kp index was low, there was a lack of solar flares and the solar flux index was high—perfect for HF. There were […]

It was business as usual last week with the solar flux index in the 180s, numerous C-class flares and, at the time of writing, 13 M-class flares over the past seven days. The Kp index has been mostly settled for this part of the cycle, averaging two to three all week. But this doesn’t mean […]

The auroral event last week was probably the strongest we’ve had in this solar cycle. There were widespread visible aurora reports from the UK on Sunday, 26 February. The Kp index eventually hit seven at 0900UTC on February, the 27th, sparking widespread visible aurora alerts all over the UK for Tuesday evening as well. The […]
Propagation News – 26 February 2023
Last week was characterised by many low- and medium-level solar flares. At the time of writing, in the past seven days the Sun has emitted more than 60 C-class flares, six M-class flares and one X-class flare. The X-class flare coincided with the measurement of the solar flux index meaning an erroneous reading of 343 […]
Propagation News – 19 February 2023
Last week was interesting as we had an X-class solar flare, and a significant geomagnetic disturbance, as well as good HF conditions at times. An impulsive X1.1 solar flare was observed around active region 3217 in the southeast quadrant of the Sun at 1548UTC on the 11 February. The flare did not appear eruptive, so […]
