COMMENT: IPS SWF HF Communications Warning 84 was issued on 24
December and is current for 24-26 Dec. Observed MUF's for the
UT day 24 Dec were near the predicted monthly values. There is
a chance of isolated shortwave fadeouts for the next two days
due to flaring potential from active sunspot regions (Region
2472 and 2473). The 2-day outlook (25-26 Dec) is for MUFs to
remain strong, near the expected predicted monthly values.
