Aims. I aim to investigate whether the photometric variability in the candidate host star CVSO 30 can be explained by starspots.
Methods. The Transiting Exoplanet Survey Satellite (TESS) light curve of CVSO 30 is separated into two independent non-sinusoidal periodic components. A starspot modelling technique is applied to each of these components.
Results. Combined, the two model light curves reproduce the TESS observations to a high accuracy, obviating the need to invoke planetary transits to describe part of the variability.
Key words: stars: variables: T Tauri, Herbig Ae/Be
