Geomagnetic Double

Post by Carbon60 » Mon Aug 04, 2014 6:18 am

Despite NOAA cancelling the CME minor storm warning yesterday, two geomagnetic events were evident and detected over the weekend on my garden magnetometer.

The 'impacts' were indeed very mild and the signal is dominated by the natural diurnal variations that occur due to induced high altitude currents generated by solar radiation as the Earth rotates in the sunlight.

These might be pre-shocks caused by faster moving plasma filaments from the CME, or they might be the main event itself, in which case we received only a very light sideswipe. Again, professional data from Chambon la Foret is used as a reference.
