Time variable H2O emission toward the 1612/1667 MHz OH maser OH 342.01+0.25 has been detected. The maser is seen in the direction of a windswept dark nebula interacting with the supernova remnant Kes 45. The maser has no optical counterpart, although it is a rather bright object in the IR (L = 2.83). The rapid temporal variations of the H2O maser suggest that the maser is associated with a young object and not a late type star. Possibly the H2O/1667 MHz OH maser originates in an object not associated with the 1612 MHz OH/IR source. If the H2O maser is young, the close association with Kes 45 may represent an example of supernova-induced star formation.
