Hi David,
thanks for that,

* it sounds promising,
* I suppose the main question now is
o if the magnetometer can detect
+ a solar flare and
+ a car then
o is there some way to tell the two signals apart/
+ by size of signal maybe
+ or shape perhaps.
* I have passing cars down the hill at my observatory
o 100m away,
o down the hill (30' - 40' lower)

We have been observing Jupiter all winter and now
we are waiting for the sun to come out of minimum.
