Last night my magnetometer recorded a nice magnetic storm. It came as a bit of a surprise – it was much more intense than I was expecting from the size of the the coronal mass ejection (CME) that sparked it. The most interesting part of the storm also happened during the local night here, so I was able to get a nice and smooth record without much noise caused by things moving around.
