The beating heart of the app. At a glance, see the three forces that govern every HF contact you'll attempt today:

Geomagnetic Kp Index — a real-time 0–9 scale of planetary magnetic disturbance, with an instant visual gauge. Green means go. Red means brace yourself.
Solar Wind Plasma — live speed (km/s) and density (particles/cm³) from the solar wind stream hitting Earth right now. When the wind picks up, propagation shifts.
Sunspot Activity — the current smoothed sunspot number (SSN), the long-cycle engine behind ionospheric skip. High SSN means the higher bands are alive. Low SSN means the low bands own the night.

All three readings update simultaneously. Pull down to refresh instantly.

X-Ray Flare Activity — GOES Satellite Feed, Direct to Your Screen
Solar flares don't knock politely. They arrive in X-ray bursts that can black out HF propagation across entire hemispheres in minutes.

QSOFlux streams the latest X-ray flux readings directly from the GOES satellite sensor and classifies every event by the universally recognized solar flare scale:

Class
Meaning
X-CLASS
Major event — potential radio blackout
M-CLASS
Moderate — degraded HF on sunlit side
C-CLASS
Minor — slight degradation possible
B-CLASS
Low — negligible effect
A-CLASS
Background — business as usual

Color-coded, timestamped to the second, and sorted newest-first. Know what the Sun just did — before it affects your antenna.

HF Band Conditions — Propagation Intelligence You Can Act On
Stop guessing which band to call CQ on. QSOFlux analyzes live Kp data and sunspot numbers through a propagation model and gives you a clear, actionable condition rating for the three major HF band groups:

80m–40m (3.5–7.3 MHz) — the night-time workhorses. Best when geomagnetic activity is low and the ionosphere is calm.
20m (14.0–14.35 MHz) — the reliable DX band. Thrives with elevated solar flux and moderate conditions.
15m–10m (21.0–29.7 MHz) — the solar-cycle high bands. Wide open during solar maximum, quiet during minimum.

Each band shows a condition label — EXCELLENT / GOOD / FAIR / POOR — along with a percentage score and the optimal operating time of day. One screen, three bands, zero ambiguity.
