BeppoSAX and ASCA observations of the field containing the γ-ray transient GRO J1838-04

We present preliminary results of Beppo SAX and ASCA observations of the Galactic field containing the unidentified γ-ray transient GRO J1838-04. Several weak X-ray sources are detected within the EGRET error box. No obvious counterpart of GRO J1838-04 is evident from these observations. More multiwavelength observations are necessary to identify the nature of this non-blazar γ-ray transient.
