Abstract (English):
The multicolour photometric observations of the dwarf nova IK Leo in 2024, carried out at the Crimean Astrophysical Observatory, are presented. We obtained a corrected value of the superhump period during the outburst, which is 0.055953 days, and studied the evolution of its changes from the plateau stage to the slow decay of the outburst. Changes in the behaviour of colour indices during the outburst are considered.
