There was an X-class flare (biggest) on the 21st (Tuesday) and at 1848UTC on the 23rd (Thursday).

Thanks for the flare info Mike. The tests were Thursday evening here so
preceded the second flare but could be longer term effects of the first one
and the other smaller flares that week. Signals over the short paths (100
to 300km) were reported as the strongest ever heard. We'll see what tonight
brings. It's never boring on these bands!
