Schumann Resonance Today
Real-Time Activity Index
The Schumann Resonance is Earth's electromagnetic heartbeat at 7.83 Hz. Check today's live Activity Index combining Schumann data from Tomsk Observatory with solar activity from NOAA.
Is the Schumann Resonance high today?
No, activity is moderate today. The Activity Index is 38 of 100.
"High" means elevated amplitude (signal power), not a change in the 7.83 Hz frequency itself. Updated hourly from Tomsk Observatory, GFZ Potsdam, and NOAA data.

Data You Can Trust
Not every spike is real
Every few weeks, screenshots of a dramatic Schumann Resonance "spike" make the rounds on social media. Some reflect real global activity. Many have a much more ordinary cause: a thunderstorm passing directly over the monitoring station in Tomsk. Lightning that close overwhelms the sensitive instruments and whites out the entire chart: the sensors are recording the storm overhead, not Earth's resonance.
The two look completely different in the raw signal. Real resonance activity brightens narrow horizontal bands at the Schumann frequencies (7.83 Hz and its harmonics). A storm at the station floods the whole spectrogram from top to bottom. ResonanceOne checks every hourly reading for exactly this signature, and cross-references flagged hours against local weather at the station.
The result: when your Activity Index is elevated, it reflects the planet, not the weather in one Siberian city. Read more about interpreting spikes in what a spike today actually means and how to read a Schumann chart without panic.
How the interference check works
Detect
Every hour, the signal is checked for the whiteout signature of a storm at the station: a flooded chart instead of narrow resonance bands.
Hold
When interference is found, the app keeps the last clean reading instead of reporting an inflated number, and lowers its confidence score until the signal clears.
Show
You see a calm storm notice, never a fake spike presented as a global event. The raw sensor value stays available in the details for the curious.
Understanding the Data
What is the Schumann Resonance?
The Schumann Resonance is a set of natural electromagnetic resonances that occur at approximately 7.83 Hz in the space between Earth's surface and the ionosphere. According to scientific literature, these resonances are primarily driven by global lightning activity, with about 2,000 thunderstorms occurring simultaneously around the world at any given moment.
First predicted by physicist Winfried Otto Schumann in 1952, these frequencies have been continuously measured since then. The fundamental frequency of 7.83 Hz corresponds to the wavelength equal to Earth's circumference, creating a natural resonant cavity between the ground and the ionosphere.
Today's Schumann Resonance activity is displayed above in our Activity Index, which combines real-time data from Tomsk Observatory with solar and geomagnetic readings from NOAA to give you a comprehensive view of Earth's electromagnetic environment.

Schumann Resonance
Real-time frequency and amplitude data from Tomsk Observatory, analyzing the 7.83 Hz fundamental and harmonic frequencies.
Kp Index
According to NOAA, the Kp index measures geomagnetic disturbance on a 0-9 scale, updated every 3 hours from 13 global observatories.
Solar Activity
Solar flare classification and X-ray flux data from NOAA's Space Weather Prediction Center, tracking solar events that affect Earth.
Why It Matters
Why Do People Track Schumann Resonance Today?
According to research published in peer-reviewed journals, geomagnetic activity correlates with biological markers like heart rate variability and sleep patterns in some populations, though the mechanisms are not fully understood. Many people report noticing subtle shifts in their mood, energy, or sleep quality during periods of elevated electromagnetic activity.
The Schumann Resonance frequency of 7.83 Hz falls within the range of human alpha brainwaves (8-12 Hz), which are associated with relaxed awareness. Some researchers hypothesize that humans may have evolved sensitivity to these natural frequencies, though this remains an active area of scientific investigation.
Tracking today's Schumann Resonance activity is not about prediction or diagnosis. It is about awareness. By monitoring Earth's electromagnetic environment, you can notice patterns, understand your own responses, and move through your day with more clarity and ease.

Research & Biology
How Schumann Resonance May Affect the Body
Research is ongoing. These are proposed mechanisms from peer-reviewed literature, not medical claims.
Brainwave Entrainment
The Schumann Resonance fundamental frequency of 7.83 Hz overlaps with the human alpha–theta brainwave boundary (4–12 Hz). Some researchers hypothesize that the brain's natural oscillatory activity may synchronize with ambient electromagnetic fields, a phenomenon known as entrainment. Alpha states are associated with relaxed awareness; theta with deep relaxation and creativity.
Autonomic Nervous System Effects
Studies published in journals including the International Journal of Environmental Research and Public Health have found correlations between geomagnetic activity and heart rate variability (HRV), a marker of autonomic nervous system balance. During elevated geomagnetic periods, some participants showed reduced HRV, suggesting increased sympathetic (stress) nervous system tone.
Melatonin and Sleep Disruption
Research by Wever (1979) and subsequent studies suggest that electromagnetic fields in the Schumann frequency range may influence circadian rhythms via the pineal gland's melatonin production. Melatonin regulates sleep-wake cycles, and disruption in its synthesis has been associated with sleep onset issues and altered dream states during geomagnetically active periods.
Cellular Voltage and Ion Channels
At the cellular level, some biophysics research proposes that extremely low frequency (ELF) electromagnetic fields, including those at Schumann frequencies, may interact with voltage-gated ion channels in cell membranes. These channels regulate calcium, sodium, and potassium flow critical to nerve and muscle function. This remains one of the more speculative but actively researched areas.

Common Questions
Schumann Resonance FAQ
Is the Schumann resonance high today?
Check the live answer block at the top of this page: it shows today's Activity Index (0–100) updated hourly. "High" readings mean elevated amplitude (signal power, usually from global lightning activity), not a change in the 7.83 Hz frequency itself. An index above 50 counts as active; above 75 as very active.
Where can I see a Schumann resonance live graph, 24/7?
Right on this page: the 24/7 live graph above shows the past 24 hours of the Activity Index, updated hourly around the clock, and the live Tomsk Observatory spectrogram shows the raw signal, auto-refreshing every 5 minutes.
Why does the Schumann resonance show a huge spike today?
Sometimes a spike reflects real global activity, but dramatic "whiteout" spikes are often false. When a thunderstorm passes directly over the Tomsk monitoring station, nearby lightning floods the sensors and saturates the whole spectrogram, which many trackers then report as an extreme Schumann event. Real resonance activity only brightens narrow bands at 7.83 Hz and its harmonics. ResonanceOne detects this local interference automatically, holds the last clean reading, and labels the hour, so a storm over one station is never shown as a global energy surge.
What is the Schumann Resonance frequency?
The Schumann Resonance is a set of electromagnetic frequencies occurring at approximately 7.83 Hz (fundamental) with harmonics at 14.3, 20.8, 27.3, and 33.8 Hz. These frequencies are created by lightning activity in the cavity between Earth's surface and the ionosphere.
How often does Schumann Resonance data update?
Our Activity Index updates hourly with fresh data from Tomsk Observatory. The Kp index component updates every 3 hours according to NOAA's measurement schedule.
Can Schumann Resonance affect how I feel?
According to published research, some studies have found correlations between geomagnetic activity and biological markers like heart rate variability. However, the mechanisms are not fully understood, and individual experiences vary. We present data for awareness, not diagnosis.
What is the difference between Kp index and Schumann Resonance?
The Kp index measures geomagnetic disturbance (0-9 scale) while Schumann Resonance measures electromagnetic resonances at 7.83 Hz. They are different phenomena: Kp tracks magnetic field disturbances from solar wind, while Schumann Resonance is primarily driven by lightning activity.
Where does your Schumann Resonance data come from?
Our primary source is Tomsk Observatory in Russia, which has provided continuous Schumann Resonance monitoring since 1999. We also incorporate solar activity data from NOAA's Space Weather Prediction Center.
