HF radio propagation today may be classified into global (average) conditions and regional (local) conditions. Figure 1 is a banner which displays today's global propagation indices made by Paul L Herrman, N0NBH: Figure 1: Solar and geomagnetic indices that influence the global conditions.

Figure 2 is a MUF 3000 km map made by Andrew D Rodland, KC2G illustrates the near-real-time regional MUFs: Figure 2: MUF 3,000 kn map Click on the map to learn more.
