TCP J02472889+6758170 = Gaia DR3 517539710877791488

The NMW team discovered this transient at 13.0 mag (unfiltered), which is associated with the known variable star Gaia DR3 517539710877791488 with ~18.0 mag. They suggest that this could be an AM CVn star in outburst. Its blue color in the Pan-STARRS1 image also supports this suggestion, and TCP J02472889+6758170 is at least a CV in new outburst.

Time-resoved observations are encouraged.
