Think this is the right thread?
A solar wind gust hit the earth during the night probably from a CME on June 14th. This event also marked my first sucsess in capturing one of these events with my home made magnetometer. Attached is an img showing my plot and part of the plot from the ACE orbiting satalite, the event is arrowed. Im also happy with how the general shape of the graphs compare. Time in bst is at the bottom of my plot.
