2B. MAGNETIC FORECAST
Date Ap Conditions
06 Mar 15 Mostly unsettled with the chance of active periods.
07 Mar 12 Unsettled
08 Mar 8 Quiet to unsettled
COMMENT: Solar wind parameters have indicated the presence of
a high speed coronal hole solar wind stream which is expected
to produce isolated active periods for 6 March.
