Whenever you do a magnetometer survey, to detect unseen objects under the ground, the optimal method is to have one magnetometer sit onsite recording the shifts in magnetic forces from the Sun, while the other magnetometer is carried across the site in a grid, recording also the time of the readings of the survey, usually automatically. You then subtract the stable magnetometer readings from the one's you surveyed, based on the time they were both recorded. Some days are not good for survey, especially around a lot of surface metal, power lines, large trains going by, tracks, debris and solar events such as this one, but could still be done. When confronted with one magnetometer, I have found that data provided online by the US government can be enough to at least know one way or the other, the "solar minimum" and "solar maximum" effects. However, this is an extreme event occurring at a "minimum" of sunspot activities which have a known 22 year cycle noted throughout the last 400 years or more. (Wikipedia entry)
