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 07168, NSV 07291, NSV 07352, NSV 07388 and NSV 07406 suspected by Luyten (1933AN....249..395L); NSV 07161, NSV 07188, NSV 07203, NSV 07208, NSV 07260, NSV 07286, NSV 07347, NSV 07387, NSV 07392 and NSV 07422 suspected by Luyten (1933AN....250..259L); NSV 07130, NSV 07228, NSV 07238 and NSV 07425 suspected by Luyten (1934AN....253..135L); NSV 07117, NSV 07131, NSV 07137 and NSV 07382 suspected by Luyten (1935AN....256..325L); NSV 07411 suspected by Luyten (1936AN....258..121L); NSV 07309 suspected by Luyten (1937AN....261..451L); NSV 07353 suspected by Luyten (1937AN....263..181L). Finding charts for these suspected variables have never been published.
