Measurement of the transit light curve of the exoplanet TOI-2570 b
The measurement of the transit light curve of the exoplanet TOI-2570 b, which was only discovered in 2022, is described. The brightness of the parent star, which is located in a very dense field of stars, was determined in 148 images in relation to comparison stars. The result agrees very well with the data known so far.
