COMMISSIONS 27 AND 42 OF THE IAU INFORMATION BULLETIN ON VARIABLE STARS Number 3908 Konkoly Observatory Budapest 22 July 1993 HU ISSN 0374 - 0676 Identification of Variable Stars in the Hubble Space Telescope Guide Star Catalogue Following with a program conducted to improve the coordinates of southern variable and suspected variable stars (see Lopez and Girard 1990), a cross identification of confirmed variables (extracted from the General Catalogue of Variable Stars -GCVS stars) and Hubble Space Telescope Guide Star Catalogue (GSC) is herein presented. Most of the stars discussed in this note are located either south of -67 degrees or in the Pav area, so this report could be considered as an extension of Lopez's (1991). and Lopez and Girard's (1990) surveys. The identification of the variables and GSC stars has been made following the procedure used by Lopez (1993). Table I shows the identifications which have been found. The first column is the designation of the variable, the second one provides the GSC number which follows the format given by Lasker et al. (1990). The last two columns give the RA and Dec (B1950). We have preferred to express the positions extracted from the GSC in the 1950 equinox-instead of the J2000 of the GSC-since it is the standard one in the GCVS. We would like to thank the Astronomical Data Center and the National Space Science Center A for Rockets and Satellites for providing a CD-ROM with the GCVS among other very useful catalogues.
