Andrew Howell, Curtis McCully, Estefania Padilla Gonzalez, Craig Pellegrino Global SN Project SN Ic 0.024755 1 Global SN Project The blue continuum with He I, He II, and C III flash features at the host redshift (0.024755; 2007SDSS6.C…0000:, via NED) suggests a young core-collapse supernova. Although the flash-dominated spectrum prevents its definite sub-type classification at this early phase, we tentatively classify it as an SN Ibn based on some similarities with SN 2019uo (Gangopadhyay et al. 2020, ApJ, 889, 170). Further follow-up is encouraged. 2020TNSCR3728....1H

Mistake in the initial classification

The correct initial classification should have been SN Ibn. We are asking the TNS team to fix it. We apologize for any confusion this may have caused.
