Как оно и было на самом деле. Подробности открытия опишу сегодня попозже отдельным постом.
CBET 4890 : 20201128 : V1112 PERSEI = NOVA PERSEI 2020 = TCP J04291884+4354232 S. Nakano, Sumoto, Japan, reports the discovery of an apparent nova (mag
10.6) by Seiji Ueda (Kushiro, Hokkaido, Japan) on six unfiltered 14-s
exposures (limiting mag 13.9) taken on Nov. 25.807 UT with a Canon EOS 6D
digital camera + 200-mm-f.l. f/3.2 telephoto lens; three confirming frames
(limiting mag 15.6) taken by Ueda with a 0.16-m f/6.3 reflector on Nov.
25.813 yield the following position for the variable: R.A. = 4h29m18s.84,
Decl. = +43d54'23".2 (equinox J2000.0). When Nakano posted the variable to
the Central Bureau's TOCP webpage, it was automatically assigned the
provisional designation TCP J04291884+4354232. Shortly after Ueda's
discovery was posetd on the TOCP, an independent discovery of this variable
at mag 10.6 on Nov. 25.844 by Stanislav Korotkiy (Ka-Dar Observatory/
Astrovert), Kirill Sokolovsky (Sternberg Astronomical Institute, Moscow
State University), and Olga Smolyankina (Omsk Observatory) was posted on
the TOCP with position end figures 18s.88, 23".3 (which yielded another
TOCP designation, TCP J04291888+4354233); they found the variable on three
20-s CCD exposures (limiting mag about 14.0) taken with a 135-mm-f.l. f/2.0
telephoto lens (and ST8300M camera) located at the Ka-Dar Observatory's TAU
Station/Astrovert, at Nizhny Arkhyz, Russia (discovery image posted at
