Our follow-up observations were obtained on 16/17 August, 2026 with the 0.7-m f/4 AZT-8 telescope at the Observational Station Lisnyky of Taras Shevchenko National University of Kyiv. On the reulted lightcurve we can clearly detected superhumps. The measured superhump period is Psh = 0.1030(73)d. The results were published in The Astronomer's Telegram.
