Wow, thanks John,
I have seen the effect accidentally ;-)
Interesting to see the time difference between Germany and the Israel
Grabber by 4X1RF :-)

Stefan,
There was a C4-level solar flare at 1220 UTC from an active region
behind the Sun's limb. Others noted the event at VLF. See:

VLF,
There are strange propagation effects going on on VLF in the last days.
I just observed that there was a significant _sudden_ rise/enhancement
of all the signal levels arround 12:15 UTC. This effect is observed on 3
spectrograms, DF6NM's 4X1RF's(some minutes later) and DK7FC's grabber so
it cannot be an accident. See the pictures.
How can this be possible? It seems the autumn and winther period
provides some interesting effects there which are not completely
understood, at least by me ;-)
