24 Jan    35    Fair-normal      Depressed 10-20% at low and 
                                 high latitudes, recovering to 
                                 near predicted monthly values 
                                 at mid latitudes.

COMMENT: Significant depressions observed at all latitudes throughout 
the UT day. Signs of recovery after local dawn today, especially 
at mid latitudes. Expect gradually improving HF conditions today 
and on day 2. However, there is a slight possibility of further 
HF disturbance today pending arrival of another mild shock in 
the solar wind. Possible further disturbance at high latitudes 
on day 3 due to a mild coronal hole wind stream effect.
