of Jan 21. They were mostly near predicted monthly values or
slightly depressed further south. The conditions are depressed
by 10% to 40% at most Australian stations this morning. This
implies depressed conditions for the remainder of the day. HF
propagation conditions are expected to be normal at low latitude
stations, and near normal to depressed at mid-latitude stations
during Jan 22.
