We observed the field of the LFBOT candidate reported by Tsuboi et al. (ATel #17646) and followed up by Gill et al. (ATel #17647), Pereyra et al. (ATel #17648), Schneider et al. (ATel #17649) and Sun et al. (ATel #17651) using the Sun Yat-sen University (SYSU) 80 cm infrared telescope. The J band observation started at 2026-02-06T14:04 (UTC), with 20s*90 exposures. We still detect the transient with a preliminary Vega magnitude of J ~ 16.5 mag, which is calibrated again the 2MASS catalog. We will continue to monitor it with SYSU 80 cm telescope.
The SYSU 80cm infrared telescope is operated and managed by the Department of Astronomy, Sun Yat-sen University.
