The case study of February 18-19, 1997 event reveals the importance of interplanetary magnetic field (IMF) horizontal components on a global magnetospheric configuration as well as on small-scale processes at the cusp-magnetosheath interface. We have used simultaneous measurements of several spacecraft operating in different regions of interplanetary space and two closely spaced satellites crossing the cusp-magnetosheath boundary with motivation to show the connection between the short and large-scale phenomena. In the northern hemisphere, observations suggest a presence of two spots of cusp-like precipitation supplied by reconnection occurring simultaneously in both hemispheres. A source of this bifurcation is the positive IMF By component further enhanced by the field draping in the magnetosheath. This magnetic field component shifts the entry point far away from the local noon but in the opposite sense in either hemisphere. The newly reconnected field lines connect the northern cusp to the quasiparallel bow shock which fills it with high-energy particles.
