Around 17.7 magnitude on June 13

I managed to find AT 2023kdb on a CCD image made by Burke-Gaffney Observatory for Pedro Jose Suarez Briones on 13 June 06:27UT at around ~17.7 magnitude.

Fading fast

I've just noticed yesterday that AT 2023kdb was clearly visible around 16.5 magnitudes on my M31 images made with a 28cm reflector of iTelescope,net on June 09.3775UT around 8 hours after the discovery.
However 3 days later, it was barely visible, faded significantly (to around 18th magnitudes).
