Abstract
We have analysed archival data taken with the Australia Telescope Compact Array (ATCA) during 2001-2003 and detected nine new interstellar and circumstellar H
2
O masers in the Large Magellanic Cloud (LMC). This takes the total number of star formation H
2
O masers in the LMC to 23, spread over 14 different star-forming regions and 3 evolved stars. Three H
2
O maser sources (N105a/MC23, N113/MC24, N157a/MC74) have been detected in all the previous observations that targeted these sites, although all show significant variability on time-scales of decades. The total number of independent H
2
O maser sources now known in the LMC means that through very long baseline interferometry astrometric measurements it will be possible to construct a more precise model of the galactic rotation of the LMC and its orbital motion around the Milky Way Galaxy.
