About this image

Poor conditions, windy and strong moonlight made the data very messy, Checked with the ExoClock admins to confirm the data was good enough and they're happy with it. This and other observations shows that the transit time is earlier than predicted - which is the whole point of the ExoClock project. This one was a  Medium priority object.
