Turned on the radio radio today and thought my RX was dead.No signals at all ,no locals nothing .A very very low noise floor on 10 meters ,11 ,12 and 15 with Just a few rumbles on 20 Had to get a friend to come up on 10 to check the gear. Had a look at a solar weather site and at the time it showed a sun spot that was expected to flair. I guess it did ! Pretty impressive shut down at my QTH.
