[vsnet-id 544] MisV1147 = HBHA 65-53

[Seiichi Yoshida <comet@aerith.net>]

Dear colleagues,

I am Seiichi Yoshida working on the MISAO Project.

As posted to vsnet-newvar, we discovered the variability of HBHA
65-53, in the catalog of Hamburg-Bergedorf H-alpha Stars in Northern
Milky Way, in the course of MISAO Project, and assigned MisV1147 to
the star.

Here is the profile of MisV1147.

MisV1147
  R.A.  22h54m03s.78
  Decl. +58o54'02".1  (2000.0)
  Mag.  12.3-13.8C
  Type  ?
= USNO-A2.0 1425.14257832  22h54m03s.745 +58o54'01".45  Mag(R):15.3  Mag(B):16.0
= HBHA 65-53  22h54m04s.0 +58o54'00"  Mag(V):13.6

Taichi Kato pointed out that HBHA 65-63 is listed in Dolidze (1959)
 Abatsu. Astrof. Obs. Bul. 24, but it is not in English.

John Greaves pointed out that it looks more or less the same
brightness on "blue", "red" and "infrared" (the N plates) from DSS
surveys, so it is probably not necessarily red object.

John Greaves also commented that it may be some type of flaring star, 
except for red dwarf, or T Tau type star if the spectral class is F, G,
or Be star if the spectral class is B. The size of the amplitude 
suggests it may be a young stellar object like T Tau, rather than B 
type star.

KenIchi Kadota pointed out that comet C/2000 SV74 (LINEAR) located 3.5
deg from this star on Dec. 8.

Anyway, the characteristics of this object is uncertain. Further
researches and comments are welcome.

Best regards,
