It is centred at 12.6° North Latitude, 354.0° West Longitude and is approximately 132 kilometres long. Based on photoclinometric analysis of Voyager 2 images (wikipedia entry)
A fossa is a long, narrow, shallow depression. On Enceladus they are named after people and places from Burton's Arabian Nights.
