Abstract

Mitaka optical and InfraRed Array second phase instrument, MIRA-I.2, has obtained the first fringes on 8th June 2002 at a baseline of 30m and the second fringes on 13th August. MIRA-I.2 consisting of two 30cm siderostats was proposed and started designing in 1994. Major constructions started in April 1999 just after the first phase instruments MIRA-I.1 was closed. The telescopes were initially put at a 6m test baseline in the MIRA-I.1 dome and obtained fringes in June 2001 and then moved to the 30m baseline in August 2001. At present, some of parts do not reach the final shape. Observations of star radii or binary orbits will be planed, while remained construction will be continued.
