MISAO Project aims to make much use of images taken all over the world for searching and tracking astronomical remarkable objects.     Nov. 15    QSO B0133+47 = MisV1436 is fainter than 15.5 mag. Optically violently variable quasar QSO B0133+47 = MisV1436 is now faint.

Please observe these stars!     We the MISAO Project need the observations of following stars. If you observe these stars, please report to Seiichi Yoshida (comet@aerith.net). MisV0814 Very peculiar variable. [Summary is in preparation] MisV1325 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. MisV1336 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. MisV1339 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. MisV1436 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. MisV1441 A T Tau type variable, a young stellar object with an H-alpha emission in a star forming region. It became brighter up to 14.5 mag in 2008 May. Eclipsing Binaries / Short Periodic Variables Campaign 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.

CCD Images Invited     MISAO Project inviting your CCD images contribution. The offered images are examined by the PIXY (Practical Image eXamination and Inner-objects Identification) system 2 developed in the MISAO Project and searched for new objects such as variable stars. The new objects will be reported to the public as collaborated discovery of the image contributors and the MISAO Project. The magnitude of known variable stars are also measured and reported as MISAO Project observations.

PIXY System 2     The automated astronomical image examination system developed by Seiichi Yoshida, used in the course of new object survey of the MISAO Project. It is implemented using Java language and it runs both on a Windows PC and a UNIX workstation. Now the version 2 of the PIXY System is being developed. The PIXY System is a free software. The source files and documents are also available. PIXY System 2 The latest version is 2007 July 15.

Variable Stars     Here introduces new variable stars discovered in the course of the MISAO Project, and the researches and analysis of variable stars by the MISAO Project. New Variable Stars The new variable stars discovered from offered images to the MISAO Project. The stars are named MisV after MISAO Project Variable stars. The number reached to 1442 on July 21.
