Australia–New Zealand HF Propagation Report — 12 August 2026:
Solar flux is modest at 95, with sunspot number 55.
Regional maximum usable frequencies remain depressed, so expect generally fair-to-poor long-haul performance, especially on higher bands. Try 20 and 17 metres during daylight, 40 metres around dawn and dusk, and 80 metres overnight; move lower if signals weaken. No HF fadeout is active, and major solar flares are unlikely.
Geomagnetic activity may increase to Kp 5 between 0600–0900 UTC as a CME and high-speed stream arrive, causing fading, noisy polar paths, auroral absorption, and unstable trans-Tasman or long-path contacts at times.
