We report follow-up observations of AT 2026aaqs discovered at 2026-09-04 08:33:25 (JD=61287.36) UT by I. Perez-Fournon and al., SGLF,
We observed the field of R.A. (ZTF) = = 00h 47m 08.004s’ DEC. (ZTF) = -20° 38’ 07.33’’ 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.
Our observations started at 2026-09-07T01-54-54, during 0,48hr, until 2026-09-07T02-20-08.
We obtained 3 sequences of 3 images exposure time 300s with Sloan-g, Solan-r and Sloan-i filters. After calibration, we made median stacked images and uploaded them 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.
