   We propose to carry out ASCA observations of the field containing the
   remarkable new gamma-ray transient GRO J1838-0415 located near the
   Galactic plane. This unidentified source was serendipitously discovered
   by EGRET in June 1995 with a very large gamma-ray flux (comparable with
   Geminga). The source was later only marginally detected in the gamma-
   ray band. We determined that no strong blazar-like radio counterpart is
   within its error box. ASCA is the ideal instrument for the
   identification of the X-ray counterpart of GRO J1838-0415.
