The geomagnetic activity remained mostly at quiet to 
unsettled levels during this period with some active 
periods on 06 June due to the effect of a high speed 
solar wind stream from a coronal hole.

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 and have been shown to be well 
correlated with rejection of high resolution aeromagnetic survey 
flight-line data.
