Sunspots are the most well-known manifestations of solar magnetic fields and exhibit a range of phenomena related to the interior dynamo. Among the observables from the spatially resolved solar disk are the number, size, and morphology of sunspots, their growth and decay, and their migration in latitude and longitude. Starspots are the direct analogs of sunspots on other stars but with the big observational restriction that we usually can not resolve other star’s surfaces. An indirect technique exists though, a technique historically called Doppler imaging. Typically, only occasional snapshots of spots on stellar surfaces are obtained while it is well-known that spots systematically change with time and, like on the Sun, only then tell us about the interior dynamo and structure of the target in question. Here we present a 16-year long time series of Doppler images for one of the most spotted stars in the sky. Creating this unique times series was only possible thanks to the continuous operation of the STELLA robotic telescope on Tenerife and its high-resolution echelle spectrograph SES. The robot has observed the star on every available clear night since July 2006, acquiring a total of over 2000 high-resolution, high signal-to-noise-ratio (S/N) spectra that are used to create 99 independent Doppler images. We combine these images into a movie visualizing XX Tri’s surface spot evolution for the past 16 years. Stellar-disk photocenter displacements of up to 24 µas, or ≈10% of the stellar disk radius, are reconstructed for XX Tri, but do not conclusively show the typical solar-like periodic behavior that could be interpreted as an activity cycle. A period of ≈4.1 yr is retrieved only from the effective temperature time series but could not be clearly confirmed from other surface tracers. It suggests a mostly chaotic, likely unperiodic, dynamo. The images also indicate missing (blocked) flux due to cool spots of up to 10% of the total flux.
