Latest Spectrogram
This past week at the Tomsk station was a bit of a mixed bag! We saw a really strong peak activity reaching 85, which is quite high, but for the most part, things were fairly calm with an average around 52. There was just one day that really stood out with that significant spike in energy.

Check statusTomsk — Siberia's sensitive ear
Tomsk is our Siberian sentinel — the most northern live station in the network, sitting deep in Russian taiga far from major power grids.
Operated by Tomsk State University, it has been sampling Schumann resonance since the mid-2000s and is one of the few stations continuously streaming its spectrogram to the public.
Its proximity to the auroral zone makes it the first station to catch incoming geomagnetic storms from the Arctic — when Tomsk wakes up, the rest of the network follows within hours. Visit sosrff.tsu.ru

Research & publicationsFrequently asked questions
How does Tomsk measure Schumann resonance?
Tomsk uses a magnetic sensor tuned to extremely low frequencies (3–40 Hz) where Schumann resonance operates. The signal is processed into a spectrogram showing frequency distribution over time, updated to sos70.ru roughly every hour.
Why is Tomsk important to our network?
Tomsk is the most northern live station in our network and closest to the auroral zone. This makes it the first station to register incoming geomagnetic disturbances from the Arctic, providing early warning for storms that will later affect the rest of the network.
When was its last major event?
Check the Notable events section above — it automatically lists the top 10 highest-score events at Tomsk from the last 30 days, each linked to a full daily report.
How reliable is the data?
Tomsk has been operating continuously since the mid-2000s and is published by a public university observatory (Siberian Physical-Technical Institute, Tomsk State University). We cross-validate its readings against other stations using our IDW weighting algorithm.
Where does the raw data come from?
The raw spectrogram images come from sos70.ru (provider.php?file=shm.jpg). We download, analyze (pixel scoring + AI narrative) and cache them every hour. You can visit sos70.ru directly for the original feed.
