Very peculiar variable.
It keeps constant for one year in 2009 by Tsutomu Fujiwara's observations.
[Summary is in preparation]
True character is uncertain.
Maybe an eclipsing variable, but maybe a RCB type variable which rarely fades out.
The variation rarely happens, so steady monitoring is encouraged.
No variation was detected in November and December by Adolfo San Segundo and Tsutomu Fujiwara's observations.
Irregular variation of 0.4 mag in a long term, and a short term small variation of 0.1 mag during several hours, were observed.
But no variation was detected by other surveys.
Continuous monitoring is encouraged.
It seems to be a popular semi regular variable in a long term.
But a minute-scale short term oscillation of 0.1 mag was also observed.
Time series photometry is encouraged.

Optically violently variable quasar QSO B0133+47.
It is recorded as a very faint object at 18-19 mag in the 20th century.
However, it was so bright as 14 mag in 2007 November.
A T Tau type variable, a young stellar object with an H-alpha emission in a star forming region.
It faded rapidly from 15.13 mag to 16.67 mag in 2009 September.
MISAO Project is operating a time series photometry campaign to obtain light curves and reveal the types and periods of new eclipsing binaries and short periodic variables discovered by the MISAO Project.
