This is an activity about the Kp index, a quantification of fluctuations in the Earth's magnetic field due to the relative strength of a magnetic storm. Learners will take a reading from a magnetometer site and make a Kp index estimate to predict whether or not an aurora display will occur near that site. This resource is designed to support student analysis of THEMIS (Time History of Events and Macroscale Interactions during Substorms) Magnetometer line-plot data. This activity requires the use of a computer with Internet access. This is activity 18 in Exploring Magnetism: Earth’s Magnetic Personality.
