Geomagnetic Activity Summary for 2018
Posted: Mon Dec 31, 2018 6:07 pm
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
