Notes:
Studies of the relationship between the optical aurorae and the ionospheric electric fields, as observed by the bi-static Scandinavian twin auroral coherent backscatter radar experiment (STARE) and the tri-static European incoherent backscatter radar facility (EISCAT), are to be undertaken in Scandinavia. For this purpose, an unmanned and fully automatic low-light-level television camera system, coupled to an all-sky lens, has been constructed. A personal computer controls all aspects of the instrument, operating it for all dark and moon-free periods. Monochrome optical data, usually at 557.7 nm, are pre-processed in real time at the recording site. The transformed images are stored digitally to magneto-optical disk with a temporal and spatial resolution directly compatible with the STARE radar data, thus making comparisons easy. Simultaneous TV recordings to tape may be made on a campaign basis. The camera has been calibrated for all gain settings, thereby permitting auroral images to be recalled in any sequence with the same absolute intensity scale. Modem communication permits remote control, trouble shooting and quick-look data transfers. © 1998 American Institute of Physics.
