Popis:	The R(2) line of the 3874 A band of interstellar CN toward zeta Oph was measured. An equivalent width of 0.120 mA implying an R(2)-R(1) rotational temperature of about 3.1 K was observed. Taking into account also earlier observations, it is found that the R(2) equivalent width is about 0.089 mA. The results imply a temperature of about 2.9 K for the cosmic background radiation at 1.32 mm.
