Have a look at

and swing the compass round to 280 degrees.

I've made no alterations to the display settings other
than to use 3-axis signals instead of 2-axis.

Compare with the 2-axis spectrogram

 http://abelian.org/vlf/fbins.shtml

to see the difference the extra channel makes.

Still processing data in background to fill in the spectrogram.
It will slowly back date to 2017-12-01 14:00, in batches, you'll
have to refresh from time to time.  It'll take a day or two to
catch up.
