COMMENT: The north-south component of the interplanetary magnetic 
field Bz, fluctuated southward by 10nT 11-16UT, then returned 
mildly northward for rest of UT day. A large south polar coronal 
hole is now moving into geoeffective position. This hole has 
had a weak geomagnetic signature on previous rotations. However, 
if Bz fluctuates southward again over the next few days an increase 
in activity may occur on this rotation.

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.
