COMMENT: IPS SWF HF Communications Warning 64 was issued on 21
December and is current for 21-23 Dec. MUFs were mostly near
predicted over the UT day 22 December. Isolated cases of sporadic
E were observed in the Australian region. Expect near predicted
values with periods of depressed conditions on 23 December due
to an expected increase in geomagnetic activity. There is the
chance of short-wave fadeouts for the next few days.
