From Satellites: Dst graph (Disturbance storm-time)

A very handy tool to characterize the strength of the magnetic field disturbance is the Dst (Disturbance storm-time). Like the Kp graph, it is very easy to read and the scientists have interpreted data from the ACE satellite for you. This data is provided in a simple 'dial' format. Below is an image of the dial with an explanation of storm levels from the Space Science Laboratory.
Note: the image below is not live data.

TEACHER'S NOTE

You may find that the Dst is sufficient for students in Grades 4-6. It is simple to read and is non-numerical. The methods used to determine the Dst values are quite complex, however, and it is best not to discuss this. The calculations depend upon Solar wind speed, solar wind magnetic field data and solar wind plasma density from the ACE spacecraft.
