When each pot was originally fired, it would have acquired a thermal remanence with a declination and inclination the same as the geomagnetic field within the kiln.
When a CME hits Earth, our planet's global geomagnetic field deflects the energy, interacts with the CME's magnetic field and funnels the solar energetic particles toward high latitude regions.
So long as the coronal hole remains open and is aligned with the Earth the geomagnetic field is disturbed with every rotation of the Sun at 27-day intervals.
Attention should be paid to one very important feature of chronobiological research--the influence of variations of the geomagnetic field.
In "The Core," geophysicists discover that the earth's geomagnetic field is rapidly deteriorating, resulting in global catastrophes that include the earth being hit by superstorms, people with pacemakers dropping dead, the collapse of the Golden Gate Bridge and the ancient walls of Roman Colosseum turning to rubble.
The SAC-C satellite, launched by the Argentine Commission on Space Activities, was designed to study terrestrial and marine ecosystems, measure space radiation and determine variability in the atmospheric structure, provide measurements of the geomagnetic field, and measure the long wavelength component of the gravity field.
MONITOR) able to: - reproduce the effects of the ionosphere in equatorial regions (temporal/spatial gradients and ionospheric scintillations) - reproduce small-scale effects such as TIDs or depletions and other disturbances - understand better the effects of geomagnetic storms in the ionosphere - adapt to changes in geomagnetic field and solar cycle - improve prediction and forecasting capabilities for ionospheric effects - understand the effects of such effects on GNSS systems Extensive measurements over solar maximum will be carried out during the MONITOR activity under the GNSS Evolutions Programme and other experiments from external organisations.

As that solar wind approaches Earth, it gets deflected by the planet's geomagnetic field and wraps around the backside of Earth, much like air streaming around a car.
