| GCVS names are announced for 14 galactic Novae discovered in 2018. |
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 (2017) announced GCVS names for 20 Novae discovered in 2015-2017. As reported in Kazarovets and Samus (2017), 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 14 Novae. For the Novae discovered in 2018, the GCVS names have not been announced in the IAU Circulars. Necessary information on the new discoveries is presented in Table 1. These stars will enter the GCVS Name-list No. 82, now already submitted.
Acknowledgments: Our GCVS work is supported, in part, by the Programme P28 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 Hitoshi Yamada, Patrick Schmeer, and other astronomers who turned our attention to discoveries of Novae not announced in the IAU Circulars.
