Using data on the equatorial boundary position of the polar oval obtained from DMSP satellites for 2010-2014 [1] and the values of solar wind parameters and geomagnetic indices during 29 magnetic storms, occurred during the selected period [2], we analyze the relationship between them. The resulting empirical dependence is compared with the previously obtained dependences on the Dst (SYM/H) and AL indices.
