Description revision of abstract at pdec, 1995 may cam01 observations are envisaged, both microscanning and staring. we believe our observational goals of monitoring the strength of cygnus x-3 and searching for the ir counterpart of the extended radio and x-ray emission are sufficiently different from the gto spring-launch goals of fmirabel that the use of the same aot should not trigger any conflict flags. these are the optimum observations for our programme. original abstract we propose observations with cam03 and cam01 (cam01 only for autumn launch so as not to clash with f.mirabel proposal) to determine both the mid-infrared spectrum of cyg x-3 and to search for extended ir emission around this source. this unusual ir-bright x-ray binary (which may be the first wolf-rayet + compact object system identified) has a near-ir continuum which may be indicative of a dense steallr wind. however, there is much uncertainty in this data and fluxes from regions further out in the wind are required. these will give information on mass-loss rates, wind structure (temp. and density gradients) etc. this object is both a candidate for the first w-r + c system discovered, and is the brightest (when in outburst) of the radio-flaring x-ray binaries with associated relativistic jets. thus this source deserves intensive study at all wavelengths.

Mission Description The Infrared Space Observatory (ISO) was the worlds first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
