[vsnet-chat 7265] MisV1336: Bright Irregular Variable

[Seiichi Yoshida]

Dear colleagues,

Kazuhiro Nakajima, Mie, Japan, discovered a new bright irregular
variable star MisV1336.

MisV1336
  R.A.   02h17m09s.27
  Decl.  +56o08'33".0  (2000.0)
  Mag.   11.26-11.68C
  Type   I
= GSC 3690-01647  02h17m09s.21 +56o08'32".2  Error:0.2"  Mag:11.99  MagError:0.41  Band:1  Class:0  Plate:01YD  Flag:F  Epoch:11 OCT 1983

The light curve suggests it is a bright irregular variable with an
average magnitude of 11.5 mag and a small amplitude of 0.42 mag.

Not only the long term irregular variation, a short term small
variation of 0.1 mag during several hours was also confirmed by the
time series photometry on three nights.

There are two entries in the NSVS catalog. The NSVS data suggests it
is completely constant at 11.60 mag. No variation over 0.1 mag was not
recorded in 1999, which suggests MisV1336 is not a periodic
variable. But the NSVS data must be blending with a southern star with
similar brightness.

Any comments on this star's type or so are welcome. Observations are
encouraged.
