N2  - The OVV blazar 3C 446 was monitored over seven months in 1997 with ground based telescopes and instruments on ESA&#39;s Infrared Space Observatory &#40;ISO&#41;. The aim was to try to detect variations in the IR and see if these were correlated with optical variations. The object varied in the optical and near-IR during this period, but did not vary in the far-IR. Despite being a factor of ten weaker than in 1983, the optical-IR SED exhibited the same slope. The new far-IR observations from ISO allow us to determine the location of the turnover in the spectrum, caused by synchrotron self-absorption. It occurs just longwards of 100 &#956;m.
