Abstract: In 2023–2024, photometric observations of three asteroids during their close approaches to the Earth were carried out using two telescopes of the Pulkovo observatory. The aim of the investigation was to obtain the lightcurves and to determine the rotation periods of the asteroids. The rotation periods were determined based on the analysis of the lightcurves obtained: two of them turned out to be extremely short (2023 BU – 77.6934 $\pm$ 1 s, 2023 DZ2 – 376.488 $\pm$ 1 s), and one was confirmed to be extremely long (1998 XB – 1913040 $\pm$ 360 s).

Keywords: asteroids, photometry, lightcurves.
