We have made measurements to determine the parallax and proper motion of the three 6.7-GHzmethanol masers G 305.200+0.019, G 305.202+0.208 and G 305.208+0.206. The combinedparallax is found to be 0.250.05 mas, corresponding to a distance of 4.1+1.2−0.7 kpc. Thisplaces the G 305.2 star formation region in the CarinaSagittarius spiral arm. The inclusion ofG 305.2 increases the Galactic azimuth range of the sources in this arm by 40◦ from Sato et al.,allowing us to determine the pitch angle of this spiral with greater confidence to be ψ = 19. ◦ 0 2. ◦ 6. The first very long baseline interferometry spot maps of the 6.7-GHz methanol maserstowards these sources show that they have simple linear and ring-like structures, consistentwith emission expected from class II methanol masers in general.
