Abstract
GN 00.33.9, on the POSS red print a barely visible nebulosity within the dark cloud L 1287, is now a well defined nebula with cometary shape. The star RNO IB, which is deeply embedded in this nebula (A v ~ 9.2 mag), shares all properties defining a FU Ori: it has brightened by at least 3 mag since 1978, its spectral type is F8I-III with a broad, variable and blueshifted P Cygni profile at Hα and broad, double-peaked absorption lines, including Lil 6707. The star coincides within errors with the cold IRAS source 00338+6312 (L[IRAS] = 440 L⊙), which drives a bipolar CO outflow.
