Andrew Howell, Curtis McCully, Stefano ValentiGlobal SN ProjectVarstarGlobal SN ProjectWe identify the source as a star due to the hydrogen absorption features at redshift zero. The star can be seen in archival PanSTARRS and SDSS images approximately 2” away from the nucleus of 2MFGC 02715.

Comments

The known star Gaia DR2 239468998260978816 (15.3 mag, distance 1,900 pc) is about 0.5" from that position.
