Interkosmos 18 (Magik, AUOS-Z-M-IK #1)

Interkosmos 18 [Yuzhnoye]

Launched during the IMS period, Intercosmos 18 experiment objective was to study the character of the ionosphere-magnetosphere coupling by continuing experiments similar to those on Intercosmos 10. Both real-time and stored data modes were used. The satellite measurements were accompanied by simultaneous ground-based, balloon, and rocket observations. The parameters were

• geomagnetic field (3 components),
• low-energy particle fluxes and their angular distributions (electrons and positive ions, 100 eV to 50 keV.,
• VLF wave electric and magnetic components (100 Hz to 16 kHz),
• electrostatic fields of magnetospheric-ionospheric origin by a double-probe technique (3 components),
• electron and ion densities and temperatures using several techniques, and
• the ion and neutral composition of the upper atmosphere.
