After a period of relative quiet in recent days my magnetometer burst into life overnight here in the UK with the arrival of an unexpected G2 geomagnetic storm. Here are my high cadence data recorded once per second, which show the rapid fluctuations in magnetic declination recorded during the event. This is presented as declination as opposed to my usual 'rate of change' because these were taken at a high sampling rate making comparisons with previous charts with a lower sampling rate (1 per 150 seconds) meaningless.
Thanks for looking.

Thanks Stuart
Is there any reason you have changed the data sampling rate?

Re: G2 Geomagnetic Storm 27th September 2022
Hi Alexandra,
I record at both sampling rates concurrently, but generally only plot the slower rate (fewer data points, quicker and easier). The slower rate is usually sufficient to capture the changes. On this occasion I decided to plot the high sampling rate data simply because I could see there were unusually rapid fluctuations in the geomagnetic record and I wanted to show these in detail.
I’ll plot the slower chart to show the difference.

1s cadence vs 150s cadence magnetometer data capture.
Lots more fine structure in the high rate captures.

Hi Stuart,
WOW, that was a good one.
