Temporal evolution of the longitudinal magnetic field (B_ℓ) from 2006 to 2023, using observations from ESPaDOnS, Narval, and SPIRou. B_ℓ and HJD measurements prior to 2023 were sourced from Morin et al. (2008), Lavail et al. (2018), and Bellotti et al. (2023). The blue circles represent observations made in the optical domain, meanwhile the pink pluses represent near-infrared observations. The text below the data points roughly indicates the year of the observations.
