Scientific paper

We are using the Very Large Array (VLA) to monitor 24 strong circumstellar 43 GHz SiO masers in the inner Galaxy, located within 2.5 degrees of Sgr A*, for estimating 43 GHz SiO maser light curves. The periods and accurate interferometric positions derived in this program will enable VLBI astrometry with the new Japanese VLBI Exploration of Radio Astrometry (VERA) array in the Galactic Center. Furthermore, as most of these stars are at a similar distance, the SiO maser light curves will put constraints on the physical properties of the maser phenomena in the expanding envelopes of these stellar objects. We present the first results from the these ongoing VLA observations, started with the VLA in D-configuration in the summer of 2004 and ending early 2006.
