is expected to be light to moderate for 20-Mar. The anticipated
arrival of a glancing blow from a filament eruption/CME on 17-Mar did
not eventuate, and it is likely the CME has passed under the Earth. G0
geomagnetic conditions are now expected. HF radio communication
conditions are now expected to be good, with maximum usable
frequencies (MUFs) generally 20-30% enhanced. Isolated minor fadeouts
possible.
