Tunguska’s trajectory and the locations of five villages projected onto a plane normal to the Earth’s surface and passing through the fireball’s approach path. The scale is given by an adopted beginning height of 100 km. Three zenith angles ZR of the apparent radiant are assumed and the trajectories plotted by the solid, dashed, and dotted lines, respectively. The parenthesized data are the distances of the locations from the plane of projection: a plus sign indicates the location is south-south west of the plane; a minus sign, north-north east of it. The transliteration of the village names in this figure and the text is consistent with that of Paper I and differs somewhat from the transliteration in the current world atlases.
