I observed it during August and September 2024 at the Skalnate Pleso Observatory. In the presentation I will give the results of the photometric observations, an estimate of the taxonomic class from tricolor photometry, and an estimate of the size of the asteroid. Together with archival data from 2010, I have also created a model of the object. From the available spectroscopy I will try to infer the surface composition of the asteroid. There will be a small bonus also.
