We present results of our survey for planetary transits in the field of NGC
6940. We think nearly all of our observed stars are field stars. We have
obtained high precision (3-10 millimags at the bright end) photometric
observations of 50,000 stars spanning 18 nights in an attempt to identify low
amplitude and short period transit events. We have used a matched filter
analysis to identify 14 stars that show multiple events, and four stars that
show single transits. Of these 18 candidates, we have identified two that
should be further researched. However, none of the candidates are convincing
hot Jupiters.
