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.
