ABSTRACT:We report new 1.2 mm continuum observations of the L183 (=L134N) dark cloud with the MAMBO bolometer array at IRAM.Combined with ISOCAM and ISOPHOT data at 7 and 200 mu m, this new observation is not compatible with the results found by Ward-Thompson et al.
(\cite{Ward94}) with SCUBA and further analysed by Lehtinen et al.
(\cite{Lehtinen03}) using ISOPHOT data.
Only one bright core, with a northern elongation (the ridge) is detected.
We show that this core has an average temperature T ~ 7.6 K +/-0.5 K which is one of the coldest temperatures reported so far.
Based on observations made with the IRAM-30m and ISO, an ESA project with instruments funded by ESA Member States (especially the PI countries: France, Germany, The Netherlands and the United Kingdom) with the participation of ISAS and NASA.
