  Geomagnetic pulsations PC1

Geomagnetic activity as reported by NOAA (http://www.swpc.noaa.gov/products/notifications-timeline)
https://dl.dropboxusercontent.com/s/a1yi31u5je7x96c/05_last-borehole-sogliano.png
The strong geomagnetic activity continues for several days, creating the right conditions for the rise of the pulse


Geomagnetic activity detected by Sodankyla Geophysical Observatory (Finland)

In the red square evidenced of a "clear from pulsation" area. This is a classical example of a middle latitude pulsation, originated at middle latitude and at frequencies up to 1 Hz. Here the north Europe observatory detects nothing, and at the same time in the south Europe all the active observatories detect the following pulsation.

Station 05 - NORTHERN CROSS RADIOTELESCOPE From Medicina (IT - Bologna), N Italy

Local noise (red square) precedes a pulsation of medium intensity (white square). Schumann resonances marked on right part.


Station 03 - ETNA RADIO OBSERVATORY From NICOLOSI (CT), Etna Park, Sicily, S Italy

Local noise (in red square) precedes the same pulsation, here detected in Sicily with induction coil. Schumann resonances marked on left part of spectrogram.


Station 04 - ROMAGNA OBSERV. From Sogliano al Rubicone(FC), N Italy.

Best network reception, with ICS101 induction coil. Geomagnetic pulsation starts at 17 and ends at 23 (white square). Schumann resonances marked on right part.


Station 04 - ROMAGNA OBSERV. From Sogliano al Rubicone(FC), N Italy.

Second part of pulsation analyzed with sonic visualizer. Structured components (the oblique lines) are clearly distinguishable.
