I had come to realise that all things magnetic were complex up there but those wildly fluctuating magnetometer graphs illustrate the point VERY well. The final dial alignment will have to wait for the sun of course but an approximation for photographic purposes was my immediate need. Hopefully we will get a glimpse of good old reliable sunshine and all will be well. Best wishes Tony M. -
