13. SVS 430 was discovered by Shajn (1934).

14. BV 964 was discovered by Knigge and Bauerfeind (1967), but their published right ascension was wrong by +12 s. Terzan and Ounnas (1988) discovered NSV 21300. We now identify NSV 08448 and NSV 21300. R = 16.5 on the DSS2 image of 1992-07-21.

15. BV 1697 was discovered by Strohmeier and Knigge (1975) and, independently, by Terzan and Ounnas (1988). R = 16.4 on the DSS2 image of 1992-07-28.

28. HV 9066 was discovered by Luyten (1935). No finding chart was available for this variable. We recovered the variable using US Naval Observatory Images. R = 14.0 on the ESO image of 1985-05-26.

29. HV 9067 was discovered by Luyten (1936). No finding chart was available for this variable. We recovered the variable using US Naval Observatory Images. R = 14.0 on the ESO image of 1985-05-23.

Remarks:
In our work aimed at improvement of the coordinates of variable stars in the NSV catalog (Samus et al. 2007-2012), we checked a number of poorly studied variables and found light elements and types for 30 of them. We were able to study the variables thanks to the publicly available electronic archives of CCD observations of the ASAS-3 project (Pojmanski 2002) and to images of the US Naval Observatory Image and Catalog Archive.
