COMMENT: Observed MUF's for the UT day 26 Dec were slightly above 
the predicted monthly values. The outlook (27 Dec) is for MUFs 
to remain strong, mostly remaining slightly above the expected 
predicted monthly values. The MUF conditions are forecasted due 
to strong incoming ionising solar flux radiation. There could 
be possible degradation of MUFs on UT day 28 and 29 Dec, if minor 
to major storms do occur within the next 24 hrs associated with 
the CME.
