Based on the provided space weather forecast and the given solar indices: - Kp = 1.00 - A = 8 - Solar Flux = 114 - Solar Wind = 350.1 km/s With a Kp of 1.00, A index of 8, solar flux of 114, and solar wind speed of 350.1 km/s, the current space weather conditions indicate relatively quiet geomagnetic and solar activity.

The X-ray flare levels mentioned (C1.2 vs B7.7) are low and not expected to significantly impact HF propagation.

In this scenario, HF propagation on the specified frequencies at 18.1575, 21.383, 24.970, and 28.470 MHz would likely be generally good.

The Solar Flux of 114 is decent for propagation, and the solar wind speed of 350.1 km/s, while slightly elevated, should not pose significant challenges.

Comparing to favorable thresholds, these conditions are fair for HF propagation but not exceptionally strong.
