Hi all, Bob Lamb let me know of this web site today, so I'll pass it on. http://www.XTRsystems.com/magnetometer/cgi/lister.pl It seems the site also shows other references. The Scientific American web sites do deliver some of the more recent (but no older articles; i.e. ~ 1996 and forward). The latest Amateur Scientist article is from March 2000. See: http://www.sciam.com/2000/0300issue/0300amsci.html For myself, part of this could be enlightening as mention is made of geomagnetic micropulsations "trains" on Roger Bakers web site. I've noticed some unusally rhythmic sine wave trains of the 4 to 10 second periods on my diamagnetic seismometer occurring sporadically, usually for some short period of time; but which do not show on my other normal seismometers.
