📋 Propagation Summary

Today’s HF propagation is looking moderately favorable for most amateur radio operators. With a solar flux around 133–154 and a sunspot number near 129–107, daytime conditions on the higher bands (20m–15m) are good, while the lower bands (80m–40m) are fair during the day and good at night. The K-index is currently low (K=2), indicating quiet geomagnetic conditions and minimal disturbance to HF propagation. Expect fair to good openings on 20m–15m for DX, with 10m and 12m more variable. Nighttime favors 40m and 80m for regional and some DX contacts. No major space weather alerts are active, so it’s a great day to get on the air!

📻 Band-by-Band Analysis

Band Morning Day Evening Night
80m 🟡 Good 🟠 Fair 🟡 Good 🟢 Excellent
40m 🟡 Good 🟠 Fair 🟡 Good 🟢 Excellent
20m 🟡 Good 🟢 Excellent 🟡 Good 🟡 Good
17m 🟡 Good 🟢 Excellent 🟡 Good 🟡 Good
15m 🟡 Good 🟢 Excellent 🟡 Good 🟡 Good
12m 🟠 Fair 🟡 Good 🟠 Fair 🔴 Poor
10m 🟠 Fair 🟡 Good 🟠 Fair 🔴 Poor

The best bands for reliable contacts today are 20m, 17m, and 15m during daylight hours, with excellent propagation expected. 40m and 80m shine at night, offering strong regional and some DX paths. 12m and 10m may open for short periods, especially late morning to early afternoon, but expect only fair conditions and be ready to switch bands if they close.

📈 Geomagnetic Conditions

The K-index has trended downward over the past 48 hours, dropping from a peak of 6 (minor storm) to a steady 1–2. This improvement means geomagnetic conditions are now quiet and stable, favoring long-haul DX and minimizing signal absorption, especially on polar and trans-equatorial paths.

📡 Propagation Timeline & Technical Details

Propagation Quality Timeline (24 Hours)

The past several months have shown solar flux and sunspot numbers holding steady in the 130–160 and 120–140 ranges, respectively. After a brief dip in May/June, both metrics have rebounded, supporting the current good HF conditions. No major solar events or storms are present in the recent trend.
