We identify the periodic transient hard X-ray source GRO J1849-03 with thetransient x-ray pulsar GS 1843-02 = X1845-024 based on the detection of x-rayoutbursts from X1845-024 coincident with hard x-ray outbursts of GRO J1849--03.Based on its spin period of 94.8 s and its orbital period of 241 days, weclassify the system as a Be/X-ray binary.Comment: 5 pages, 3 figures, accepted for publication in the Astrophysical Journal Letter
