Andrew Howell, Curtis McCully, Craig Pellegrino, Estefania Padilla GonzalezGlobal SN ProjectSN0.061316Global SN ProjectWe note the blue continuum of this object, its fast rise (as seen in the ZTF lightcurve), and its absolute magnitude (g-band absolute magnitude roughly coeval with spectrum of -18.5). This object could be a young SN II, or possibly a fast blue optical transient (FBOT). Further followup is encouraged, as is refining this classification as the object evolves further.2020TNSCR1164....1B
