We report the detection with ROSAT of a transient X-ray source at R.A. and decl. 17h44m33s.1 [28¡44@29A (J2000), which we identify with the transient bursting pulsar GRO J1744[28. We have made K-band observations of the X-ray source at ESO and the US Naval Observatory, Flagsta† Station. A K-band counterpart of this transient previously identiÐed by us on an image taken 1996 February 8 by Blanco et al. is found to be detected during only two (of seven) short exposures of which this image is composed. We cannot deÐnitely reject the reality of this variable object but feel that it is not possible to rule out an instrumental e†ect. The lack of a persistent K-band counterpart of GRO J1744[28 is consistent with the idea that the low-energy emission from this object is dominated by reprocessing of X-rays in an accretion disk. Subject headings : pulsars : individual (GRO J1744[28) È stars : neutron È X-rays : stars
