Hi, Antonio,

I regularly note the geomagnetic Kp value when I take part in an FMT 
but most of the discussion of this takes place on K5CM's FMT-nuts mail 
list (as far as I know).  Fortunately, most FMTs have not coincided 
with a major storm but there have been a few where some really weird 
effects were noted, probably due to "minor" disturbed geomagnetic
