Short summary
This study, for the first time, convincingly attests to the two-step geospace storm being the best possible solar–terrestrial event of opportunity for realizing a technique for estimating the interplanetary magnetic field (IMF) Bz component threshold for the formation of the substorm current wedge. The data from INTERMAGNET magnetometer network on the two-step geospace 23–24 April 2023 storm yield the IMF Bz threshold for the formation of the substorm current wedge of –(22–30) nT.
