We report follow-up observations of AT 2026zzd discovered at: 2026-08-29 15:38:32.064 (JD=2461282.15176) by Jianlin Xu and al. (XOSS).  
We observed the field of the AT 2026zzd (AR +18h 19m 18.34s DEC -14° 03m 42.5s) with our Planewave-CDK17 telescope at AITP-Observatory (W96) at SPACEOBS San Pedro de Atacama in Chili equipped with a CMOS QHY268M camera and Sloan filters g-r-i.

Pictures sequences have been calibrated and stacked in a median sum with AstroimageJ uploaded to STDWeb, (Karpov, S., 2025; Lechapelain, P.-Y., 2026). The images were calibrated using the reference catalog Pan-STARRS DR1 for Sloan filters and Hotpants for galactic subtraction.  
We obtained:
