Abstract
We present, results from a new (CO)-C-12 (J = 1 --> 0) survey of the l ambda-Orionis region. The observations cover 110 square degrees unifor mly on a Nyquist-sampled grid. We discover CO emission at levels far l ower than possible in previous surveys, revealing a structure similar to that seen in IRAS 100 mu maps. We derive a total molecular mass of 1.1 x 10(4) M.. A possible explanation for the isolated and localised outbreak of star formation in the region is discussed.
