SRS: Spectral Resonance Structures

SRS  From 11AUG15-2000 to 12AUG15-0800 UTC
Detected by Monitoring St. 04 - ROMAGNA OBSERV.ATORY From Sogliano al Rubicone (FC), N Italy.

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

Low geomagnetic activity level. SRS time is indicated in purple oval.  Any sign of activity there.


Geomagnetic activity detected
by Kiruna Geophysical Institute (Sweden ) http://www.irf.se/maggraphs/puls.php
 
As before,
low geomagnetic activity level. SRS time is indicated in white oval, with any sign of activity there.

The ignition source of the SRS is identified in Aegean Sea: a large storm cell positioned between Greece and Sicily (white oval). With crosses purple are indicated
VLF monitoring stations.

Source file:

Monitoring St. 04 - ROMAGNA OBSERVATORY From Sogliano al Rubicone(FC), N Italy. 

ICS101 induction coil, Schumann Resonances marked on left part. Strong and clear SRS appear below first Schumann resonance, below 4 Hz. 



Monitoring St. 04 - ROMAGNA OBSERV.ATORY From Sogliano al Rubicone(FC), N Italy. 

Source file analyzed with sonic Visualizer. Schumann resonances marked on left. Spectral resonance structures clearly visible in the zoomed view in white oval.


Monitoring St. 04 - ROMAGNA OBSERVATORY From Sogliano al Rubicone(FC), N Italy.

Induction coil. Daily strips representation. SRS are also visible in past and following days.


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

ULFO induction coil. Schumann Resonances marked on left part. SRS weaker evidenced in white oval. The two monitoring stations are nearby but the sensors are oriented in a different way.

   
Monitoring St. 01 - IK1QFK  CUMIANA (TO), NW Italy 

Two orthogonal ICS101 induction coils. Schumann Resonances marked on left part. SRS weaker evidenced in white oval. This station receives in all directions, but it is more distant from the origin point of the signal. The blue-green color of the weak SRS, which here corresponds to the coming direction, indicates correctly that the signal is coming along NW / SE axes.
