Be complete: While LF, MF and HF bands experiment blackouts, the
increasing of the electronic density between 50-90 km aloft at daytime
(due to solar flares) enhances VLF communications during a few days.
I've seen reports in ham related groups of good propagation on LF as well
as 10 meters lately.
