From DEMETER satellite passing strong storm instead of from strong storm moving/developing near stationary receiver (similar pattern). See http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.724.1356&rep=rep1&type=pdf Figure 1 for better image; and Figure 3 for what satellite spectrogram could approach with ideal receiver. As expected, Stefan’s image surpasses DEMETER.

That is a beautiful image!
Maybe I should print it out and hang it on the wall?
Yes, do that. I often had the same idea. I have downloaded some images during the last years. Spectrograms, not only of QRSS but also of EbNaut transmissions. It reminds me on these times and feels like watching photos from the past...

Hi VLF,
It was quite a noisy night with several local lightnings, leaving
interesting traces in the H field, attached.
