Time series of longitudinal magnetic field and activity indices measurements for HD 63433 from the Neo-Narval observations. The longitudinal field (top panel) exhibits intermittency in the sign of the magnetic polarity, which is symbolic of a likely complex or non-axisymmetric topology. The Hα index (middle panel) does not exhibit strong variations, while the Ca II IRT index (bottom panel) has an increased scatter towards the latest observations. The Hα and Ca II IRT indices show correlated temporal evolution.
