Using the IRAM PdBI-WIDEX with 3.6GHz band width, we serendipitously detect an emission line at 150.6 GHz. From a search over 14.5 GHz in the 3-mm and 2-mm atmospheric windows, we confirm the identification of this line as CO(5-4) at z = 2.816, meaning that it does not reside in the z~2.30 proto-cluster in this field.
