Positional reference stars in the Magellanic Clouds
The equatorial coordinates are determined of 926 stars (mainly ofgalactic origin) in the direction of the Magellanic Clouds at the meanepoch T = 1978.4 with an overall accuracy characterized by the meanvalues of the O-C coordinates, Sa = 0.35 arcsec and Sd = 0.38 arcsec,calculated from the coordinates of the Perth reference stars. Thesevalues are larger than the accuracy expected for primary standard stars.They allow the new positions to be considered as those of reliablesecondary standard stars. The published positions correspond to anunquestionable improvement of the quality of the coordinates provided inthe current catalogs. This study represents an 'astrometric step' in thestarting of a 'Durchmusterung' of the Magellanic Clouds organized by deBoer (1988, 1989).

Primarily Galactic stars with high radial velocity near the Magellanic Clouds
UBV photoelectric measurements and spectral types (sometimes revised)are presented for 54 mostly-foreground high-radial-velocity stars nearand between the SMC and LMC. The color-color diagram is shown to be verysimilar to that of Omega Cen. It is noted that four of the stars aresubdwarves, 23 stars are submetallic or horizontal branch stars, onestar is probably a member of the LMC, and the rest are population Istars of luminosity classes III-V. The density of high-velocityforeground stars towards the Magellanic Clouds appears to be about 20times higher than in other directions of similar galactic latitude.
