Comments:


2. The ASAS-3 range is for the combined brightness of the Mira and its neighbor.

3. R = 16.4 on the DSS2 AAO of April 27, 1993. The ASAS-3 range is for the combined brightness of the Mira and its neighbor.

5. USNO-A2.0: R = 15.9.

6. This star was found, upon our request, by D. Williams on Harvard plates.

7. The ASAS-3 range is for the combined brightness of the Mira and its neighbor. P = 701.1d and M type of variability in the ASAS-3 variable-star catalog (Pojmanski 2002).

8. The RR type was erroneously suggested by Hoffmeister (1965).

9. This star was found, upon our request, by D. Williams on Harvard plates.

10. The ASAS-3 range is for the combined brightness of the Mira and its neighbor.

13. USNO-A2.0: R = 16.7.

14. USNO-A2.0: R = 15.9.

15. R = 15.7 on the DSS2 AAO of July 27, 1992. The ASAS-3 range is for the combined brightness of the Mira and its neighbor.

18. USNO-A2.0: R = 16.0.

19. USNO-A2.0: R = 15.5.

20. USNO-A2.0: R = 14.8. The ASAS-3 range is for the combined brightness of the Mira and its neighbor.

25. R = 16.0 on the DSS2 AAO of July 27, 1989.

Remarks:
We could 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 Catalogue Archive (http://www.nofs.navy.mil/data/FchPix/). We recovered the variables NSV 07168, NSV 07291, NSV 07352, NSV 07388 and NSV 07406 suspected by Luyten (1933a); NSV 07161, NSV 07188, NSV 07203, NSV 07208, NSV 07260, NSV 07286, NSV 07347, NSV 07387, NSV 07392 and NSV 07422 suspected by Luyten (1933b); NSV 07130, NSV 07228, NSV 07238 and NSV 07425 suspected by Luyten (1934); NSV 07117, NSV 07131, NSV 07137 and NSV 07382 suspected by Luyten (1935); NSV 07411 suspected by Luyten (1936); NSV 07309 suspected by Luyten (1937a); NSV 07353 suspected by Luyten (1937b). Finding charts for these suspected variables have never been published.
