| GCVS names are announced for 20 galactic Novae discovered in 2015-2017. |
According to an agreement between the team of the General Catalogue of Variable Stars (GCVS; Samus et al. 2017) and the Central Bureau of Astronomical Telegrams (CBAT) reached in 1998, GCVS names for galactic Novae and some other variable stars of special interest can be given, upon BAT suggestion, between regular Name-lists of Variable Stars. These GCVS names are supposed to be announced in IAU Circulars or Central Bureau Electronic Telegrams and then enter the next regular Name-list. This practice meets approval of the astronomical community, new names begin to be frequently used by researchers immediately after the variable's discovery.
Kazarovets and Samus (2015) announced GCVS names for 13 variable stars (Novae and stars of other rare types, ZAND and FU) discovered in 2013-2015. These names were also included into the GCVS Name-list No. 81 (Kazarovets et al. 2015ab). As reported in Kazarovets and Samus (2015), recent Novae, currently often initially announced not in the CBAT sources, frequently remained not noticed by the CBAT at all.
The present paper announced official GCVS names for 20 Novae. Only for nine of them, the GCVS names have already been announced in the IAU Circulars (Kazarovets and Samus 2016abcdefg; Samus and Kazarovets 2017ab). Necessary information on the new discoveries is presented in Table 1. These stars will enter the GCVS Name-list No. 82, now in preparation.
The case of V1658 Sco needs a special explanation. This is the star OGLE-2015-NOVA-01, which we erroneously named V5852 Sgr and communicated this name to the team investigating the star (cf. Aydi et al. 2016). Since the coordinates of the star correspond to the constellation Scorpius, we follow our usual practice and recommend using the name V1658 Sco as the permanent one for this Nova in future.
Acknowledgments: Our GCVS work is supported, in part, by the Programme "Transitional and Cataclysmic Processes in Astrophysics" of the Presidium of Russian Academy of Sciences. We have made use of information resources provided by the ASAS-SN survey (Shappee et al. 2014; Kochanek et al. 2017). We would like to specially thank Dr. Hitoshi Yamada and other astronomers who turned our attention to discoveries of Novae not announced in the IAU Circulars.
