A hot Jupiter discovered by amateur astronomers, confirmed through citizen science collaboration.
A full transit of KPS-1 b was observed on January 20, 2025 using differential photometry with the 203mm RC telescope. The light curve shows a clean 14.2 mmag dip lasting 2.12 hours, consistent with the published ephemeris. This observation was submitted to the ExoClock project to help refine transit timing predictions for future ARIEL mission targets. The mid-transit time was determined to within 45 seconds of the predicted value, confirming no significant transit timing variations.
