The UNSW Automated Patrol Telescope has been under-
taking a search for extrasolar planets using the transit method.
We show light curves from two recent promising candidates;
spectroscopic follow-up using the ANU 2.3m shows that the
companions are possibly low mass stars rather than planets,
although more data will be needed to be certain. We outline
future improvements to our transit search: a hardware upgrade
scheduled for 2006, and the application of trend-filtering algo-
rithms to the existing data.
sited at Siding Spring Observatory (SSO), Australia. From
February to May 2005 we observed a pair of fields centred
on 12h 0 , -36d 0 , obtaining 22 nights of good data (RMS <
4mmag for stars brighter than 10th magnitude). Lightcurves
for close to 3000 stars brighter than 13th magnitude were
compiled, and two promising candidates designated UNSW-
TR-13 and UNSW-TR-14 were discovered. UNSW-TR-13
