Description
We could study the variables thanks to the publicly available electronic archives of CCD observations of the ASAS-3 project (Pojmanski, 2002, Cat. <II/264>) and to images of the US Naval Observatory Image and Catalogue Archive (https://www.usno.navy.mil/USNO/astrometry/optical-IR-prod/icas). We recovered the variables NSV 07017 and NSV 07082 suspected by Luyten (1933AN....249..395L); NSV 07106 suspected by Luyten (1933AN....250..259L); NSV 06939, NSV 06975, NSV 06991, NSV 07011, NSV 07025, NSV 07035, NSV 07045, NSV 07047, NSV 07051 and NSV 07062 suspected by Luyten (1934AN....253..135L); NSV 06907, NSV 06946, NSV 07022 and NSV 07083 suspected by Luyten (1935AN....256..325L); NSV 07106 suspected by Luyten (1936AN....258..121L). Finding charts for these suspected variables have never been published.
