HiNOTORI: Hiroshima 50cm telescope project in Tibet area

Michitoshi Yoshida, Yousuke Utsumi and Koji, S., Kawabata (Hiroshima University)

We report the current status of HiNOTORI (Hiroshima uNiversity Operating Tibet Optical Robotic Imager) project, which is a 50cm optical telescope project at Gar site in Tibet. The main purpose of this project is to conduct short- and long-term observations of transient objects including gamma-ray bursts, supernovae, blazars, etc. with UV-optical three color (u', R, I) imaging. This is also a pilot program for developing future world-wide electro-magnetic follow-up network of gravitational wave transients. Gar site is located close to the western edge of Tibet. The site testing data have indicated that this site would be one of the best astronomical sites in the world. Since there is no large astronomical facility around the Tibet area, the location and site condition of the site are thus very much valuable for 24 hours observations of transient objects. We report instrumentation and recent progress of HiNOTORI project. In addition, we show some results of site testing measurements of Gar site performed by us.
