📋 Propagation Summary
Today’s HF propagation is looking solid for most operators! With a solar flux of 158 and sunspot numbers holding at 125, the higher bands (20m–10m) are offering good daytime conditions for both local and DX work. Low geomagnetic activity (K-index at 1) means stable propagation and minimal disruptions. Expect excellent opportunities on 20m–15m throughout the day, with 12m and 10m also open for longer periods. Nighttime brings the low bands (80m, 40m) back into play for regional and some DX contacts. Take advantage of the quiet geomagnetic field for reliable signals and low noise!
💡 Operator Tips
- Daytime: Focus on 20m, 17m, and 15m for the best DX and intercontinental contacts.
- Nighttime: Switch to 80m and 40m for strong regional and some long-haul paths.
- Digital modes (FT8, FT4) will help you snag weak-signal DX, especially on 10m and 12m.
- CW and SSB are both performing well—try SSB on 20m–15m during peak hours.
- Contesters: Plan for high activity on 20m–15m during the day and 40m at night.
- Antennas: Multi-band verticals and dipoles will shine—make sure your antenna is tuned for the higher bands.
⏰ Best Operating Times
- 80m & 40m: Best at night and early morning (local time)
- 20m: Excellent all day, especially late morning to afternoon
- 17m & 15m: Open most of the day, peaking around midday
- 12m & 10m: Good during late morning through afternoon, may close after sunset
🌍 DX Opportunities
- 20m–15m: Strong DX paths open across Europe, Africa, and the Americas during daylight hours.
- 10m & 12m: Watch for short, sporadic E and F2 openings—especially around local noon and early afternoon.
- Grayline: Enhanced propagation on 40m and 20m at sunrise/sunset—chase rare DX along the terminator!
- No major aurora activity expected, so polar paths remain stable.
- Special events: No warnings or alerts—enjoy the calm!

- Nights: 80m and 40m become the go-to bands, offering good conditions for local and some DX work.
- Worst bands: 80m and 40m are poor during the day; 10m and 12m are poor at night.
📊 Current Solar Activity
Solar Activity Metrics
K-index
Solar Flux (10.7cm)
Sunspot Number
- K-index: 1 – Very quiet geomagnetic field, ideal for HF propagation and low noise.
- Solar Flux (10.7cm): 158 – High solar flux means strong ionization, supporting higher band openings.
- Sunspot Number: 125 – Healthy sunspot count keeps the upper bands active and supports DX.
- Space Weather Overview: No significant flares or disturbances; X-ray flux at B8.2 is low, indicating stable conditions.
📈 Geomagnetic Conditions
- The K-index has remained mostly low (1–2) over the past 24 hours, with only brief bumps to 3–3.7.
- Trend: Conditions are stable to improving after minor unsettled periods—no geomagnetic storms.
- Impact: Expect minimal absorption and fading, especially on polar and trans-equatorial paths.

Solar Wind Speed
Aurora Activity
- X-ray Activity: B8.2 (low)—no risk of HF blackouts or sudden ionospheric disturbances.
- Solar Wind Speed: 444 km/s—moderate, but not enough to trigger geomagnetic storms.
- Electron Flux: 2220—elevated, which can enhance daytime MUF and support higher band openings.
- Proton Flux: 17—quiet, no radiation storm concerns.
- Aurora Level: 1—very low, so auroral propagation is unlikely; VHF/UHF bands remain unaffected.
- Helium Line: 123.8—steady, indicating no major solar trend changes.
📡 Propagation Timeline & Technical Details
Propagation Quality Timeline (24 Hours)
- Recent months show a slight downward trend in both solar flux and sunspot numbers, but current values remain strong enough for robust HF propagation.
- Solar flux has ranged from 160 (Dec) to 135 (Feb), with sunspot numbers following a similar pattern.
- Current conditions are still favorable for high-band activity, but keep an eye on the trend for possible gradual decline as we move forward.
