Abstract
The AMPTE artificial comet of 27 December 1984 developed a well-defined core (maximum size ∼160 × 100km) of cold barium ions, surrounded by a diffuse coma, 500km in diameter, consisting of ions extracted from the core. A plasma tail extended from the core, mainly directed away from the Sun. The plasma tail and diffuse coma consisted of energetic ions (>200 eV). Confounding predictions, the artificial comet survived for barely 5 minutes, and the core of the comet moved southward, rather than in the direction of the solar wind
