The source is aligned with an SDSS galaxy at z=0.078 and it shows an extremely fast rise (>2.9 mag over less than two days between the most recent upper limit and the first detection) to a high luminosity (M_g~-19.8). 2023TNSTR1152....1H N

Andrew Howell, Curtis McCully, Megan Newsome, Estefania Padilla Gonzalez, Giacomo Terreran Global SN Project SN Ibn 0.0768 1 Global SN Project The spectrum, obtained 11 days after discovery, shows narrow He I emission on top of a broader, asymmetric base. This feature is consistent with circumstellar interaction, as seen in Type Ibn SNe. The profile of this line is different from the H alpha line in the spectrum, which is likely due to host contamination. Over the last week the B-band light curve, measured by Las Cumbres Observatory, has fallen by roughly 0.1 mag/day, consistent with the evolution of Type Ibn SNe. 2023TNSCR1279....1P
