   XTE J1855-026 was discovered during RXTE PCA slews of the Galactic
   plane. Followup PCA observations showed pulsations at a 362 second
   period and enabled a moderately accurate position to be determined.
   With this position, it was then possible to obtain an ASM light curve
   which showed a, presumably orbital, modulation at a period of 6.1 days.
   The source had first been suspected to be a Be star system. However,
   this combination of pulse and orbital periods is more typical of a
   supergiant wind accretion driven system. We propose here to study the
   spectrum, in particular the iron line, and refine the position of the
   source. The iron line properties will help determine whether this is a
   supergiant or Be type system. The improved position will aid in
   searches for the optical counterpart.
