000007124 520__ $$aThe Ca II K and H lines are used to monitor a large number of stars, including the Sun. The viewing angle under which the star is observed impacts the visibility of magnetic structures and hence the integrated flux measured. We have modelled the impact of the inclination angle on Ca II K plages time series on the detection of short and long-term modulations. For this, we have reconstructed the solar disk under different viewing angles from full-disk images recorded at the Royal Observatory of Belgium with the USET telescope between 2012 and 2024. We will discuss our work and its implication for monitoring Sun-like-stars.
