The picture shows the latest available webcam image; the webcam looks southwest from the attic window towards Saint Leonard over the corner of our orchard and over one of our fields.
You will need to refresh the web page (F5) to update it. If the image is black then the webcam may be still working and hopefully it is just the night scene (but if it is working properly during darkness it should show a message saying the camera is offline)!
If you click on the image it will take you to a web page where the webcam image is updated automatically every minute during daylight hours. That page also includes another webcam showing a thermometer displaying the current outside temperature (the probe is about 6m above ground level).
