Further examination of the Data from the Hp component (the perpendicular geomagnetic
field component) as available at:
http://sec.noaa.gov/ftpdir/lists/geomag/20011106_G8mag_1m.txt
shows the effects beginning a few minutes before originally described. Effects on
the geomagnetic field begin to increase Hp strongly about 03:53-03:54 UT instead
of originally estimated - 03:57.
Why is this difference in three minutes important? It may be a smoking gun
in the geomagnetic triggering hypothesis because at Coalinga at 03:54 UT
just as the CME hit, two events of Ml 2.4 nd 2.8 were recorded followed about
an hour later by a third event at 04:38 UT which incidentally was also associated
with at strong change in the total and horizontal geomagnetic field.
The Three Coalinga quakes occurred as follows:
O: 6NOV2001 4:38:36 36.2N 120.3W ML=2.7 NCSN NNE of Coalinga, CA
O: 6NOV2001 3:54:51 36.2N 120.3W ML=2.4 NCSN NE of Coalinga, CA
O: 6NOV2001 3:54:13 36.2N 120.3W ML=2.8 NCSN NNE of Coalinga, CA

You can be the judge whether this is coincidence of if the evidence is mounting
for a direct causal relationship.

I would be very curious if any of you heard ear tones at this time.
