Derivation of the 3D Structure of Flares in the Homologous Flare Series of 1992 February

In February 1992, three flares, which we consider constitute a homologous flare series, occurred in the active region NOAA7070, and were observed by the Yohkoh SXT. In this paper, we discuss the 3D structure of arcade type flare by making use of the different perspectives of the flare in the homologous flare series.
