Solar Conditions
📖 Interpretation Guide
- SFI
- Solar Flux. Ionosphere health. (>70 is OK)
- SN
- Sunspots. More sunspots, better propagation.
- A
- Daily magnetic stability. (Lower is better)
- K
- Current magnetic disturbance. (0-2 Ideal)
- X-Ray
- Solar flares. (High values cause blackouts)
- 304A
- Extreme UV radiation. (F-layer ionization)
- Ptn Flx
- Proton Flux. (Affects noise at the poles)
- Elc Flx
- Electron Flux. (Affects satellites)
- Aurora
- Probability of auroras at high latitudes
- Aur Lat
- Minimum latitude affected by the aurora
- Bz
- Magnetic field. (+ Stable / - Unstable)
DXLook Reception Radar — K4DDI
Reception and Propagation Analysis — This map visualizes radio frequency activity captured at various locations with 24/7 receivers. The converging lines represent real radio signals that have traveled from remote transmitters to our antenna, using the ionosphere as a natural mirror.
- Data Source: Hybrid integration of WSPR, PSK Reporter and Reverse Beacon Network (RBN) reports.
- Active SDR: Simultaneous monitoring on 8 HF bands via KiwiSDR.
- Antenna System: Inverted-V dipole optimized for 20 meters.
- Interpretation: Line thickness indicates signal strength (SNR). Openings from Europe or Asia indicate exceptional ionospheric conditions.
