   The past year has seen independent discoveries of the two Galactic
   sources showing super-luminal motion, GRS1915+105 and GRO J1655-40.
   We have observed these two sources with ASCA, and discovered
   characteristic absorption line features. These features are unique in
   that they have never been seen from other persistent X-ray sources,
   and may be a signature of superluminal jet sources. We propose to
   observe GRS1915+105 using ASCA in conjunction with regular BATSE and
   radio observations. We plan to search for possible relations between
   absorption line features and hard X-ray or radio emission.
