МНЕ ПРИШЛО СООБШЕНИЕ ...
Кидайте в переводчит все кто не знает английского..))
Я посмотрел - Район вспышки Новой Центавра у меня просматривается на 2-х камерах в предрассветных лучах... ))) О! - Sechr Gut !!! Сейчас промеряем ....

AAVSO Alert Notice 492

Nova Centauri 2013 = PNV J13544700-5909080
December 4, 2013

Event: Nova in Centaurus = Nova Cen 2013 = PNV J13544700-5909080

Discovered by: John Seach (Chatsworth Island, NSW, Australia)

Discovery magnitude: unfiltered magnitude 5.5 using a DSLR with
50-mm lens

Discovery date: 2013 December 02.692 UT

Coordinates: R.A. 13 54 45.34 Decl. -59 09 04.2 (2000.0, K. Hornoch,
Astronomical Inst., Ondrejov, Czech Republic)

Spectra: Low-resolution spectra obtained by Malcolm Locke
(Christchurch, New Zealand) on Dec. 03.3776 UT and by Rob Kaufman
(White Cliffs, NSW, Australia) on Dec. 03.621 UT show strong Ha
and Hb emission lines, indicating the object is a nova. Spectra
URLs below.

Charts: Charts for Nova Cen 2013 may be created using the AAVSO
Variable Star Plotter (VSP) at http://www.aavso.org/vsp.
Selecting an 'A' scale chart will give the widest choice of
comparison stars for this very bright object. Choosing the
Binocular chart option along with the 'A' scale will result in a
less cluttered field and is recommended. Alternatively, setting
the 'Field' option at 580 (arcmin) and 'Magnitude limit' at 8.0
will give a smaller field of view but still provide many bright
comparison stars.

At present, however, Nova Cen 2013 has brightened beyond the
comparison stars available on even an 'A' scale chart. It is
recommended that observers use:
41 = eta Cru (HD 105211) V=4.142, B-V=+0.353
40 = zeta Cru (HD 106983) V=4.043; B-V=-0.174
39 = gamma Mus (variable with 0.02 mag. range) V=3.85; B-V=-0.155

Electronic observers are cautioned to be careful not to saturate
the nova. Since the comparison stars are mostly fainter than the
nova, it is recommended to take short exposures and stack them so
as to achieve a good S/N for the comparison stars without saturating
the nova. Electronic observers should not use gamma Mus.

star (located at 1.538 arcsecond from the transient) to this
position in the USNO-B1.0 catalogue is USNO-B1.0 0308-0442031,
mag. B2=15.52 R2 =15.12. B. Skiff (Lowell Obs.) reports preferred
coordinates (2000.0) for this possible progenitor are
13 54 45.35 -59 09 04.1 (UCAC2) and 13 54 45.35 -59 09 04.1 (2MASS).
Skiff also notes that there is an XMM-Newton x-ray source 2" away.

Henden comments that there is a close companion to the NE that
will be a problem as the nova fades, but is not a factor now.


Congratulations to John Seach on his latest discovery!

Hi Ivan,

Those observations have been changed to CV.

Minsk seems to be ideally placed for catching bright novae! We are too far north to see if from here (I am in Ireland now).

Best regards,
Sara

ПЕРЕВОД

Привет Иван,

Эти замечания были изменены, чтобы резюме.

Минск, кажется, идеально подходит для ловли яркий новых звезд! Мы слишком далеко на север, чтобы увидеть, если отсюда (я нахожусь в Ирландии в настоящее время).

С уважением,
Сара

Иван Брюханов

Здравствуйте Георгий Михайлович!
02/12/2013 вспыхнула Новая Центавра около Бэта Центавра...
В то время как отдельные наблюдатели просмотрели звезду 1-2 раза _ Брюханов сегодня за вечер и ночь просмотрел и измерил её блеск и отправил в ААВСО 11 точек на график, зафиксировав дважды более ранние моменты Новой в блеска около 6.5 величины, чем первооткрыватель....)))

Новая Центавра 2013 - явно не спешит слабеть ...
Это уж точно не быстрая Новая и не похожа на Новую Дельфина 2013
:-X

[MarsianskiAlien]

Возможно, будет похожа на Новую Геркулеса 1934 года..

[bis]

Да, Ваня ...
Я не могу себе приписывать снижение блеска Новой Центавра - она явно на рассвете "пучится-ярчает" как любая красная переменная...
Т.е. звезда цветная - наверняка избыток инфракраса как тогда у Новой Дельфина - чёй то вкладывает ...))) Так как все эти снимки без фильтра и внесистемные, а матрицы пик чувствительности имеют в красных лучах ...

Но это однозначно не тип NA.

НОВАЯ ПОРЦИЯ НАБЛЮДЕНИЙ 10-14 декабря 2013
