Ap and ap are unitless and can be multiplied by 2 nT to yield the average geomagnetic disturbance at 50 degree geomagnetic latitude. # Kp, ap and Ap were introduced by Bartels (1949, 1957) and are produced by Geomagnetic Observatory Niemegk, GFZ German Research Centre for Geosciences. # Described in: Matzka et al.
