2B. MAGNETIC FORECAST 
Date      Ap    Conditions
08 Jan    12    Unsettled, chance of active periods. 
09 Jan    13    Unsettled, chance of active periods. 
10 Jan     4    Quiet to unsettled 
COMMENT: A coronal hole may cause a very mild increase in geomagnetic 
activity may be experienced 8-9 Jan, although recurrent patterns 
suggest this is unlikely.
