LF: Magnetometer uses

["Talbot Andrew" <ACTALBOT@dera.gov.uk>]

I have been given a small compass module that, apart from magnetic heading, gives a serial digital high resolution output of X and Y components of the Earths magnetic field.  Added a simple PIC + S/W to give the outputs in text formatted RS232 for connection to a PC.  Whilst idly thinking of something to do with this (apart from a remote compass on my antenna)  I wondered about a 2 axis magnetometer monitoring for solar storms etc.

 

Does anyone on this reflector (Alan ?) know what sort of magnetic field changes are a precursor to magnetic storms, and what sort of sampling interval it is worth averaging over to automatically alert on these.  I could easily log X / Y data to disc at a regular interval, write an alerting function etc etc.  if there is any worthwhile research advantage in doing so.   Otherwise the module will be relegated to being used on 10GHz portable operations, for aiming my dish remotely.
