The changes in coordinates are minimal. There is no need for new Confirmation Charts. A 3D view of massive cluster formation in the SMC This is a 5-orbit astrometric proposal designed to measure for the first time the internal dynamics of NGC347, the super-OB-association in the Small Magellanic Cloud. Regions of massive-star formation are important to study because they are intricately related to the origin of the stellar-mass distribution and the formation, evolution and possible disruption of open and globular clusters. Despite its relevance, the process whereby stars form in massive star clusters is still poorly explored terrain within astrophysics. By combining our new observations with archival ACS/WFC data acquired in July 2004, we will be able to (1) measure the relative proper motions of NGC346 sub-clusters better than 3 km/s; (2) investigate the nature of the apparently isolated massive stars found around NGC346; (3) identify runaway OB stars with proper motion velocities >9 km/s and also establish their probable points of origin. Combined with radial velocities (RVs) from the "VLT-FLAMES Survey of Massive Stars", our observations will allow us to determine the 3D dynamics of NGC 346. This work will address significant open issues in: star formation, cluster dynamics, the origin of isolated Type II supernovae and GRBs, and the role of massive star feedback on the interstellar medium. This is an astrometric proposal aimed to measure proper motions in a massive star-forming region in the Small Magellanic Cloud. Observations are designed to duplicate data acquired in 2004 by Nota et al. in program GO-10248. In order to minimize uncertainties we ask to use exaclty the same orients and dither patterns used in Nota's program.
