Hi All
What we got at about 9 UTC was an intense flare peak reaching R2

Looks like since then I’m getting less ground noise in my grabber. Specially in the lower frequencies
like the 50Hz window at the bottom of my grabber
https://ea5dom.ure.es/grabber/index.html
The drop of noise is clearly seen also in the 8270Hz and 4270Hz 3.8mHz FFT windows at Stefan’s VLF grabber
I keep transmitting in MF during the day. But no signs of inono refelections due to flares

Hi Roelof,
Very interesting. It also affects VLF! Clearly visible e.g. at
http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber2.html
It happens since about 9 UTC.
Would have been interesting to observe the propagation on 8.27 kHz during that time...

Hello all,
Now something different:
It looks like a severe radio black out of HF is ongoing.
I have never seen this before. See attachment.
This is also an opportunity to look at PLC interference at the lower
bands, which is normally covered by signals.
I checked it on 3 different antennas: mini-whip, loop and
hf-doublet.
