| Description | we propose a series of 15 iso observations to monitor the ir variability of the blazar 3c279, contemperaneously with other observations at gamma ray, x-ray and optical wavelengths. iso observations made in pv phase have shown that the synchrotron break frequency lies inside the iso range. determinaton of the break frequency is a key diagnostic of synchrotron and synchrotron-self-compton models. our proposed observations would; - measure the exact synchrotron break frequency, and search for flux-dependant variations of that frequency; - search for possible variations in ir flux and spectral slope; - search for possible correlated variations between the ir continuum properties and those at other 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. |
