Yes, making your own measurement is very different from just looking at
graphs & data on the internet. I'd love to copy your instrument one day.

Thanks, Dieter. This little home brew magnetometer never ceases to amaze me. It tracks very well with the "big guys" in Canada's observatory. On a quiet day, it pretty much takes the form of a parabola. Yesterday it really demonstrated the buffeting the magnetosphere took from the solar wind. Invariably when spaceweather.com posts photos of brilliant auroras in the northern hemisphere, it shows disturbances. Just a 3cm x 10mm x 10mm neodymium magnet over a linear Hall effect device, suspended by a silk thread inside a glass jar. It sits on a concrete patio for stability. I wish I were smart enough to get the Arduino to time stamp it! It records onto an ordinary camera SD card, and is read by Excel.
When the Chihuahuas walk close to it, their metal ID tags cause a little "bump" in the trace!

I had to drop down to 15m to hear any of the IARU beacons. Yesterday's magnetograph us attached. It covers 0100Z Monday thru 0100 yesterday.
