OH maser emissions associated with a star formation region NGC 6334 F at 1665 and 1667 MHz were observed in right and left polarization with the VLBI MK III recording system. The strong emissions were found to come from an area with a linear size of 5 x 10 to the 15th cm. The majority of the maser features were seen projected near the head of the comet-shaped H II region. A velocity gradient of 6-10 km/s/arcsec is found in the velocity-position plot. This suggests a rotating disk in which a young OB star with a mass of about 25 solar masses is being formed.
