A couple of CMEs linked up producing one (so called CME cannibalism). Even so, the result (so far) has been only a G1 geomagnetic storm, although there could be more to come since a G3 was expected according to NOAA models https://www.swpc.noaa.gov/products/wsa- ... prediction
Here are my magnetometer data collected yesterday and overnight (30th-31st).
Clearly the event is still in progress, so it will be interesting to see what happens over the coming hours.
Thanks for looking.
Stu.

Excellent Stuart, the movie is in Sunlit Earth section

Re: G1 Geomagnetic Storm 31st March 2022
Hi Stuart,
Trying to understand all this I found a few days ago some measurements done by the NASA using two satellites in Space.
Comparing their data as below to yours and looking at the same time on you March 13th - 14th graph I see today it was 10 times weaker.
The graph from GOES gives a maximum value of 183 and 121 nT. So interpolating this by ten times for March 13th - 14th on that days the maximum value could have reached maybe 1500 nT (taking an average of both values before).
I will ahve to talk to my friend in order to connect an Arduino to my coil and save data every minute and then graph it and compare.
I know I know my coil are not temperature stable and not free from surrounding EMI but would be interesting to see the graph and compare.
Maybe I am to naive in thinking I can detect anything

Re: G1 Geomagnetic Storm 31st March 2022
Hi Rainer,
I find the best source of useable data is from Intermagnet (a global geomagnetic observation network). You can plot out geomagnetic data from a station near you, for whatever date you choose.
https://www.intermagnet.org/data-donnee ... ot-eng.php
I often use their values to 'calibrate' my own charts.
For East-West measurements, use their 'Y' values. To give you an idea of the scale of the expected magnetic declination effect, on a quiet day the range might be of the order of +/- 10 nT, on a day with mild geomagnetic unrest then you might see +/- 20-40 nT and during storms you might see something of the order of +100/-50 nT or similar. These figures depend on your latitude, of course, so nothing is set, but it gives you an idea of how relatively small these deviations are when compared with Earth's magnetic field strength of 25,000- 65,000 nT.
I hope this helps
Stuart
