Date   T index  Conditions       MUFs                              
05 Jan    30    Normal-fair      near predicted monthly values 
06 Jan    20    Normal-fair      about 10% below predicted monthly

COMMENT: HF frequencies were overall near monthly medians across 
the region, albeit with some variations, strong at equatorial 
latitudes and some dusk enhancemments at mid-latitudes. Near 
median MUFs may be expected for the next 1-2 days before mild 
geomagnetic activity from a coronal hole may suppress frequencies 
on day 2. Sporadic E-layer activity re-occurred but less extensive 
and intense than yesterday, Similar Sporadic-E may continue over 
the next few days.
