Three-dimensional trajectory of CD-30°11223 in a Cartesian Galactic coordinate system with the z-axis pointing to the north Galactic pole. Current positions of CD-30°11223 (blue ⋆), Sun (black ⊙), and Galactic centre (black +) are marked. The approximate point in time of the supernova explosion is symbolized by the red asterisk, while the arrow marks the position of the Sun at that time. Solid lines indicate the future 42 Myr, dashed lines the past 150 Myr. CD-30°11223’s kinematic properties are obviously those of the local thin disc population.
