We observed the field of the candidate LFBOT reported by Tsuboi, Nakaoka,
& Kawabata (ATeL #17646) with the 80cm Tsinghua-NAOC Telescope (TNT, http://www.xinglong-naoc.cn/html/gcyq/80/detail-27.html ) at the Xinglong Observatory of the National Astronomical Observatories of China on 2026 February 6.
TNT imaged the position in B, V and R bands. The data were analysed
with AstroImageJ. We detect the transient with the following magnitudes:
B = 16.61 +/- 0.04 at 11:01 UT with a 300s exposure
V = 16.50 +/- 0.04 at 11:06 UT with a 300s exposure
R = 16.46 +/- 0.04 at 11:11 UT with a 300s exposure
B = 16.84 +/- 0.04 at 15:48 UT with a 300s exposure
V = 16.59 +/- 0.04 at 15:53 UT with a 300s exposure
R = 16.65 +/- 0.04 at 15:58 UT with a 300s exposure
