SUPERNOVA 2005cs IN M51
 
     Wolfgang Kloehr, Schweinfurt, Germany, reports his discoveryof an apparent supernova (mag about 14) on CCD frames taken with a0.20-m reflector on June 28.907 and 28.928 UT, with a weak earlierimage of the new object (at mag perhaps 16) also found by Kloehr ona frame taken on June 27.933.  Kloehr gave the position for SN2005cs as R.A. = 13h29m53s.37, Decl. = +47o10'28".2 (equinox 2000.0),which is 15" west and 78" south of the center of M51 (= NGC 5194).Nothing was visible at this location on earlier frames taken byKloehr on May 11 and 26, on an `LRGB' image taken by R. Muendleinon Feb. 5, or on a Digitized Sky Survey image.  W. Li, Universityof California at Berkeley, reports that a CCD image taken with theKatzman Automatic Imaging Telescope (KAIT) at Lick Observatory onJune 30.25 confirms the new object at mag about 13.5; Li providesposition end figures 52s.85, 36".3, which is 67".3 south of thenucleus of M51.  A KAIT image taken on June 15.20 showed nothing atthis position (limiting mag about 19.0).  H. Yamaoka, KyushuUniversity, reports that K. Itagaki (Teppo-cho, Yamagata, Japan;0.60-m telescope) obtained the following position end figures forSN 2005cs from an unfiltered CCD image taken on June 30.484, whenthe new object was at mag 14.3:  52s.78, 35".7; nothing was visibleat this location on Itagaki's image taken in poor conditions onJune 20.598 (limiting mag 17.0).

 Izvinite, chto bez perevoda, ya seychas v poxodnix usloviyax ::)

Eshe rano o chem-to govorit'. Po spektoru etu SN prichislili k II tipu - u nix bolee dolgii period pod'ema i padeniya bleska po s ravneniyu s I tipom, ne isklucheno plato v oblasti max bkeska ili lineynoe padenie bleska. Gal', chto ne pekulyarnaya SN(((
 Nado podogdat' xotyabi nedelu, chto bi opredelit'sya s krivoy bleska ;)

 Пока блеск поднимается, а я все ни как не переведу многие статьи, что уже успели накатать зарубежные ученые - они ведь в январе 2005 года проводили фотосьемку М51 на Космическом Телескопе им. Хаббла ;) Вот и полилась широким ручейком информация о возможных моделях Предсверхновой  :D
