[time-nuts] Phase noise and geomagnetism

Hi Antonio you must remember the "static" geomagnetic field is around 
50,000nT and the biggest Solar induced events are around 500nT  so the 
effect might be difficut to detect as  events of this size are not very 
common.  More common events are in the 100 to 200nT range.
