Measurement of the transit light curve of the exoplanet TOI-1516b on March 20/21, 2025
The measurements were taken from 10:39 PM UTC on March 20, 2025, to 3:34 AM UTC on March 21, 2025, in Osnabrück, Sonnenhügel. The moon was 64% illuminated and 115° distant. It rose at approximately 1:15 AM UTC on March 21, 2025, but only reached a maximum altitude of 9° above the horizon. It was therefore of little relevance for the measurement.

Measurement of the transit light curve of the exoplanet TOI-4137b on March 19/20, 2025
The measurements were taken from 7:19 PM UTC on March 19, 2025, to 12:39 AM UTC on March 20, 2025, in Osnabrück, Sonnenhügel. The moon was 74% illuminated and 133° distant. It rose at approximately 12:15 AM UTC on March 20, 2025, and was therefore hardly relevant for the measurement.

Measurement of the transit light curve of the exoplanet TOI-1259Ab on March 18, 2025
The measurements were taken from 12:14 a.m. UTC on March 18, 2025, to 4:32 a.m. UTC on March 18, 2025, in Osnabrück, Sonnenhügel. The Moon was 87% illuminated and 103° distant. It set around 6:05 a.m. UTC. Sunrise was already around 5:30 a.m. UTC, which is why measurements could only be taken until about half an hour after the end of the transit.

Measurement of the transit light curve of the exoplanet HAT-P-12b on March 7/8, 2025
The measurements were taken from 9:42 PM UTC on March 7, 2025, to 2:00 AM UTC on March 8, 2025, in Osnabrück, Sonnenhügel. The moon was 64% illuminated and 87° distant. It set around 4:25 AM UTC.

Measurement of the transit light curve of the exoplanet Qatar-10b on March 5/6, 2025
The measurements were taken from 11:28 PM UTC on March 5, 2025, to 4:11 AM UTC on March 6, 2025, in Osnabrück, Sonnenhügel. The moon was 43% illuminated and 80° distant. It set around 1:00 AM UTC.

Measurement of the transit light curve of the exoplanet TOI-2154b on March 4/5, 2025
The measurements were taken from 7:20 PM UTC on March 4, 2025, to 12:16 AM UTC on March 5, 2025, in Osnabrück, Sonnenhügel. The moon was 28% illuminated and 63° distant. It set at 12:20 AM UTC. During the measurement, some cirrus clouds passed through.

Big, black, hot and with a short life expectancy
The measurement of the transit light curve of the exoplanet Wasp-12b is described. This exoplanet is special in many ways. The large number of existing transit light curves, including our own measurements, enables spectacular predictions about the lifespan of the exoplanet.

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.

TrES-3b, HAT-P-18b, TOI-2154b and TOI-1251.01
The measurements of the transit light curves of the exoplanets TrES-3b, HAT-P-18b, TOI-2154b as confirmed and TOI-1251.01 as unconfirmed exoplanet are described. Each of them has peculiarities that make it worthwhile to take a closer look at them.
