      Hobart              31   (Quiet to unsettled)
Pc3 pulsations are high frequency (10-45 second period) variations 
of the Earths magnetic field. Daily pc3 indices are the daily sum 
of 20 minute pc3 indices for that station.

Estimated AFr/Ap Indices 14 Jul : A 
           Fredericksburg        18

2B. MAGNETIC FORECAST 
Date      Ap    Conditions

                periods. 
16 Jul    20    Unsettled with active and possible minor storm 
                periods. 
17 Jul    16    Unsettled to active 
COMMENT: A coronal hole solar wind stream is expected to impact 
the Earth during 15 July and result in mildly elevated geomagnetic 
activity levels, with isolated minor storm levels possible.
