An exceptionally faint carbon star has been found at a high galactic latitude. The star continuum is weak and poorly exposed shortward of 4400 A. The Swan C2 bands at 4737A, 5165A, and 5635A are of only moderate strength while the red CN features appear to be very weak. There is no evidence of emission in the hydrogen lines. The color index and the low-dispersion spectral characteristics point to an R-type classification. It is suggested that the star might be associated with the Magellanic Stream. At an assumed upper limit for the distance of the Stream of about 50 kpc, the star would have a luminosity comparable to that observed for some Population II, R-type stars in globular clusters and in the LMC.
