Henny,
 
this is an excellent capture! The noise bands surely match the Wikipedia description of the Schumann modes http://en.wikipedia.org/wiki/Schumann_resonances.
 
What is the speed (pixels per second) of your spectrogram? It seems that distinct flashes (the Q-bursts?) are visible in the lower two Schumann bands.
 
Best regards,
Markus (DF6NM)
