We report follow-up observations of SN 2026aaiv discovered at 2026-09-01 11:23:32.352 (JD=2461284.97468) by J. Tony and al., ATLAS.
We observed the field of R.A. (J2000) = 22h 37mn 05.618s / DEC. (J2000) = +34° 24’ 35.37’’
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 2026-09-04T01-36-43 during 1.31hr
We obtained 3 sequences of 12 images exposure time 120s 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 or ZOGY for galactic subtraction.
