Abstract

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 mmag at the bright end) photometric observations of ~50000 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 is a convincing hot Jupiter.
