 Best Quiet Periods: 13 Apr to 15 Apr,  20 Apr to 21 Apr,  26 Apr to 30
Apr.

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.
