Latest exoplanet transit observation for the ExoClock project. Transit time is pretty close to the predicted one.
Terrible seeing which meant guiding was mostly >1" instead of the usual 0.5" and strong moonlight. So the data was not the best but the software managed a decent fit. The HOPS software is excellent.

Edit: this is the transit fit processed by the ExoClock team and shows an error in predicted transit time of 1.1 minutes.

Predicted
magnitude: 11.025
depth: 0.01584
duration: 2.22 h
