Andrew Howell, Curtis McCully, Estefania Padilla Gonzalez, Craig PellegrinoGlobal SN ProjectSN Ic0.024755Global SN ProjectThe 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

Comments

Object coordinates updated according to AT-report 92720 of Group Pan-STARRS1
Previous RA, DEC: 09:26:02.258, +24:31:17.83 (141.509406667, +24.52162)
Updated RA, DEC: 09:26:02.262, +24:31:18.07 (141.509425482, 24.521685394)

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.
