Hi Folks,
It's the end of 2018 and time for a summary of the geomagnetic activity recorded during 2018 on my home brew magnetometer here in the North-West of England. I've had a few short 'outages' with one thing or another, so the record is not as complete as I would have liked, with February and December being particularly weak on usable data. Nevertheless, the record does display the various intermittent bursts of activity that occurred throughout the year from holes in the Sun's outer atmosphere (corona) and consequent fast flowing solar wind. Mostly the resulting storms were weak (G1) with an occasional G2, but all of them resulted in aurora.
The data have been plotted as raw 'rate of change' over time, in arbitrary units, together with running average of these data as a means of smoothing.
I hope you find this interesting.
Thanks for looking.
Happy New Year to all.
Best wishes for 2019
Stu.

Re: Geomagnetic Activity Summary for 2018
Both equinox zones looked the most interesting again, it is a good record to use to help plan an aurora holiday I hope the problems with the magnetometer are all sorted now?
Happy New Year!

Good stuff Stu! The coronal holes are certainly produce the goods when it comes to aurora. We're off aurora hunting at the end of October, fingers crossed one of those coronal holes is about then.

Thanks, Alexandra/Mark.
All up and working again It took a day or two to get to the bottom of the problem, which I attributed to a noisy power supply. Good luck in October, Mark.

Re: Geomagnetic Activity Summary for 2018
Noisy power supplies are bad things. They give us more noise in our imaging (USB power) and make our hifi systems sound worse than they should. Now here's one playing havoc with your magnetometer. We got a 'hive' light bulb, and, depending where we plug it in depends on how much it flickered, all down to noisy power.

Re: Geomagnetic Activity Summary for 2018
That’s an impressive record, Stu.
How does it compare with a solar active year?
I agree with Mark. Noisy power supplies are bad things! Often times very difficult to diagnose.
Cheers and Happy New Year.

Thanks, Peter.
My records don't go back far enough, unfortunately. I'm looking forward, though, to the next cycle to see how it builds from solar minimum.

It certainly kept me guessing for a while......
