Schumann Resonance Live

Data gaps present in today's record.

Today the resonance monitor shows a mostly calm blue background with the main Schumann resonance bands clearly tracing across the day, and the lower bands (around 7.8 Hz and 14 Hz) running a bit brighter at times, suggesting mildly elevated global thunderstorm energy feeding the Earth–ionosphere cavity. There aren’t prominent vertical white columns spanning many frequencies, so there’s no strong signature of nearby lightning discharges dominating the record. A few thin, steady horizontal lines sit at fixed frequencies, which is typical man-made interference from power/industrial sources rather than natural resonance changes. Late in the day the display turns into a solid black block, indicating a data gap where the station stopped recording.

• All five modes visible. Horizontal bright bands at 7.83, 14.3, 20.8, 27.3, and 33.8 Hz confirm active resonance across the full tracked range.
• Consistent band spacing. Even separation between modes indicates stable ionospheric geometry with no significant compression or expansion events.
• Diurnal intensity cycling. Brightness fluctuations track the rotation of global thunderstorm centers through their daily peak output windows.

Fundamental at 7.95 Hz — within normal range.

• Stable trace near 7.83 Hz. Reflects normal ionospheric geometry and cavity dimensions consistent with quiet geomagnetic conditions.
• Upward shifts above 8.0 Hz signal ionospheric compression from solar UV/X-ray flux increases or sudden geomagnetic disturbance onset.
• Downward drifts toward 7.5 Hz typically occur during local nightside passes when the ionosphere expands to higher altitude, enlarging the cavity.

F1 amplitude at 4.0 — typical signal power.

• Clear diurnal cycling expected. Africa peaks ~15:00 UTC, South America ~20:00 UTC, Southeast Asia ~08:00 UTC as each region's convective storms intensify.
• Brighter regions indicate stronger power. Sustained high-brightness periods may indicate mesoscale convective complexes or tropical cyclone genesis events.
• Seasonal variation is normal. Northern Hemisphere summer produces overall higher amplitude due to greater continental landmass heating and thunderstorm frequency.

Q-factor at 7.3 — healthy energy retention, cavity ringing cleanly.

• Values of 4 – 8 are nominal. Healthy energy retention with the cavity ringing cleanly at each harmonic mode.
• Drops below 4 indicate increased absorption. Caused by enhanced solar X-ray flux during flares or energetic particle precipitation during geomagnetic storms.
• Values above 8 signal exceptionally clean conditions. Typically seen during geomagnetically quiet intervals near solar minimum.
