We show a phase-referenced image of the SiO maser emissions towards the Mira variable R Aqr. These data have been obtained using the VLBI Exploration of Radio Astrometry (VERA). The proper motion we have obtained is different from that obtained using the HST. The proper motion from 2004 to 2005 is not different from that of 1991 to 2005 and supports the current orbital elements.
