I too saw the magnetic effect of this flare using a UKRAA MAgnetometer in Kent. I have been told that the sharp dip and recovery seen in the Inclination signal is called a magnetic crotchet due to its resenblance to the musical note. I have not seen an extended SID like dip as seen in the declination signal before.
Today the magnetometer is starting to move away from a quiet day profile. Aurora tonight?
