28 Jan   120    Normal           Near to 15% above predicted 
                                 monthly values

COMMENT: Maximum Usable Frequencies (MUFs) in the Australian 
and Antarctic regions were near predicted monthly values to 15% 
enhanced. MUFs are expected to be near predicted monthly values 
to 15% enhanced over 28-29 Jan, with geomagnetic activity from 
a small coronal hole high speed wind stream effects. Mostly near 
predicted monthly value are expected for 30-Jan.
