We present results from our survey for planetary transits in the field of the intermediate age ( \sim 2.5 Gyr ) , metal-rich ( [ Fe/H ] \sim +0.07 ) open cluster NGC 6819 .
We have obtained high-precision time-series photometry for over 38,000 stars in this field and have developed an effective matched-filter algorithm to search for photometric transits .
This algorithm identified 8 candidate stars showing multiple transit-like events , plus 3 stars with single eclipses .
On closer inspection , while most are shown to be low mass stellar binaries , some of these events could be due to brown dwarf companions .
The data for one of the single-transit candidates indicates a minimum radius for the companion similar to that of HD 209458b .
