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 16 Jun : A 
           Fredericksburg         8
           Planetary             10

17 Jun     8    Quiet to Unsettled 
18 Jun     8    Quiet to Unsettled 
19 Jun     8    Quiet to Unsettled 
COMMENT: Solar wind parameters indicate the presence of a weak 
coronal hole solar wind stream over the past 18 hours. Geomagnetic 
activity is expected to remain at quiet to unsettled levels for 
the next few days.
