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.  See:
