Hi Stefan et al.,

Impressive image!

A comparable effect could be observed here at Kiel, North Germany, at 2018-04-22 on the broadband LF-rx (15cm ferrite loop). See:

Interesting detail: just before the local onset of that thunderstorm an unusual sudden increase in field strength of DCF77 (77.5 kHz) and DCF49 (129,1 kHz) could be observed. Both transmitters are located near Frankfurt, bearing 190 deg. from here.

73 de df3lp,
Peter
