Here below the first LIVE
spectrogram, updated 30 minutes.
Marconi Antenna + Geophone
Amplitude scale: two channels listed below.
Picture, every 30 minutes, shows last
8 hours. All date and times are in UTC.
Electric filed multistrip daily
representation, useful for comparing anomalies from day
Scroll time 110 sec, updated every 30
minutes, FFT frequency resolution 10.5 mHz.
Geophone Multistrip hourly
representation, useful for local seismic events
Scroll time 4.6 sec, updated every 60
minutes, FFT frequency resolution 112 mHz
Here below the same data elaborated as plotting traces. The picture shows the last 30 hours, and values are detected every 150 s.
Picture, updated every 30 minutes. Four traces are reported:
Panoramic view captured from my garden, and a couple of Induction coils, orthogonally placed, inspected by a hen.
ULF magnetic field
Spectrum scale: magnetic components of the spectrogram below with long term average curve (red) and last waterfall line. Frequency range 0.1 – 35 Hz, with a sensitivity of 1 pT at 1 Hz, here with a 30 Hz low pass filter turned ON.
FFT resolution 10.5 mHz, scroll time
40 seconds. Schumann resonances are almost always
visible at night. During the daytime the signal from a
single track railway line, which runs 4 km from the
monitoring station, prevails. A few kilometres away
there is also a 380 kV high-voltage power distribution
Induction coil multistrip
spectrogram, for shorter time event representation.
Magnetic field received by induction coil. FFT with 84
mHz resolution, scroll time 4.5 sec. More than 4
hours are showed. Picture updated every 30 minutes.
Multistrip daily representation,
useful for comparing anomalies from day to day:
Scroll time 110 sec, 7 mHz FFT resolution, updated every 30 minutes.
