Opera 2015 - Magnetic Pulsation 008

2015-03-20 22:45 to 23:45  Geomagnetic pulsations PC1

Geomagnetic activity as reported by NOAA (http://www.swpc.noaa.gov/products/notifications-timeline)

The strong geomagnetic activity continues for several days, creating the right conditions for the rise of the pulse


Geomagnetic activity detected by Nurmijarvi Geophysical Observatory (Finland) http://www.sgo.fi/Data/Pulsation/latestPulsation.php

Geomagnetic activity detected throughout the day. Various pulses (in white squares). In the red box that stronger.

Station 01 - IK1QFK  CUMIANA (TO), NW Italy

The same pulsation above in red box received here in Italy with two orthogonal induction coils ICS101. Structured lines are visible in the bottom spectrogram. In the picture the colors of the pulse change: it means that the phase of the propagation changes with frequency. First two Schumann resonances marked on right part of spectrogram. Spectrogram processed with SpectrumLab RDF function.

Station 01 - IK1QFK  CUMIANA (TO), NW Italy

Same file, processed with sonic Visualizer: North-South direction on top, East-West on bottom.


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

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


Station 05 - NORTHERN CROSS RADIOTELESCOPE From Medicina (IT - Bologna), N Italy
Same file, processed with sonic Visualizer: hence the structure of the pulsation is very clearly visible.
