As part of our survey of the Messier 31 galaxy, we spotted a new, faint variable star on images taken on 15 Jan. 2024. Checking our archives, we could confirm this as a real variable source.

The new variable star is visible in the animation below, making clear its brightness variation.

The source is placed at the following J2000. coordinates:

VTP J004017.96+404852.3 C2024 01 15.734 00 40 17.95+40 48 52.4          19.7 R

At the position above a very blue, faint source (with no flags of variability) is present in the Pan-STARRS Consortium DR1.
