We report photometric follow-up observations of thirteen exoplanets (HATS-1
b, HATS2 b, HATS-3 b, HAT-P-18 b, HAT-P-27 b, HAT-P-30 b, HAT-P-55 b, KELT-4A
b, WASP-25 b, WASP-42 b, WASP-57 b, WASP-61 b and WASP-123 b), as part of the
Original Research By Young Twinkle Students (ORBYTS) programme. All these
planets are potentially viable targets for atmospheric characterisation and our
data, which were taken using the LCOGT network of ground-based telescopes, will
be combined with observations from other users of ExoClock to ensure that the
transit times of these planets continue to be well-known, far into the future.
