[vsolj-alert 192] New (eruptive?) object in Tri



New (eruptive?) object in Tri

 超新星捜索中に以下の(爆発型?)新天体を発見したとの報告がありました。
 光度からはこの銀河団の超新星よりも、我々の銀河系の爆発型変光星(たとえば
 矮新星)の可能性が考えられます。DSSに写っていないとのことで、変光振幅
 は6等以上となり、もし矮新星であった場合、またまた「大アウトバースト」の
 UG型である可能性があります。ただし、画像と座標の位置が合わないのではな
 いかとの指摘もあり、注意が必要です。

  Hello:

  Our names are Maximo Suarez and Inmaculada Gomez, we are members of
Asociacion de Variabilistas de Espan~a (AVE) and Astronomical Association
of Gran Canaria.

  During a supernova photographic patrol inside the Abell's Galaxy Cluster
262, we found an stellar object in this position:

Ep. 2000.0   R.A.: 01h 51m 13.3s, DEC: +3606' 00" 

The photographs are:

Aug 23.2 UT, 15 min exp, Mv=15.0, Magnitude limit was 15.5
Aug 27.1 UT, 20 min exp, Mv=13.7, Magnitude limit was 16.0
Aug 31.1 UT, 13 min exp, Mv=14.0, Magnitude limit was 14.5

  The photographs were taken in Gran Canaria (Canary Islands, Spain) at
1850 meters high, with a S/C 0.20m f/10 and Kodak TMAX-3200 negative films. 
The magnitude limits are variable for the differents atmospheric conditions
and exposure time.

  No object or star brighter than magnitude 16.0 appears at this position
in the Palomar Sky Survey, GSC or Simbad. No variable is catalogued in
GCVS and no asteroid or comet is present for that dates and position (CBAT
and ICQ database). 

  I am sending you a scanned image of 27.1 Aug attached to this message.

  Good nights.

  Maximo Suarez.

About the suspected SN in Abell 262, I intend to give some basic
information.  

The cluster Abell 262 has z = 0.0161, from which the normal SNeIa at
this distance would be expected to be about 15.7 mag at their maximum
light.  Reported magnitude was 2 mag brighter than this. 

The center of the cluster is 1h52m.8, +36o08' (2000.0, Abell et al.
1988).  The location of the new star is about 24' west and 2' north
from the cluster center.  In the neibour of the reported position,
there is a (spiral?) galaxy UGC 1319 = PGC 6865 = IRAS 01485+3549.  
>From its core, the reported star is at an offset of 190" west and 124"
north.  

Sincerely Yours,
