Line emission at 87.057 GHz attributed to the J = 1..-->..0 rotational transition of the formyl ion HC/sup 17/O/sup +/ has been detected in Sgr B2 (OH). The HC/sup 18/O/sup +//HC/sup 17/O/sup +/ abundance ratio found (3.1 +- 0.6) is lower than the terrestrial /sup 18/O//sup 17/O elemental abundance ratio (5.5) and agrees, within the errors, with the C/sup 18/O/C/sup 17/O and /sup 18/OH//sup 17/OH abundance ratios observed in that source.
