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.

COMMENT: Recent CME activity does not appear to be Earthward 
directed and quiet to unsettled geomagnetic conditions are expected 
to persist for the next few days.
