Jenna Karcheski, Kishore C. Patra, Ryan J. Foley (UCSC) report/s a classification of object: SN 2026ikn
Type: SN IaRedshift: 0.298
Remarks: We report the classification of AT 2026ikn from spectroscopic observations with the Keck Cosmic Web Imager (KCWI) Integral Field Spectrograph. Observations were made on 2026 May 7 UT. Redshift was determined using emission lines from the host galaxy. Classification was performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024). The spectrum is highly contaminated by galaxy light. SNID template fitting was performed after subtracting a host-galaxy template spectrum. The best-fit match was SN 2005hf at +15 days past peak brightness.
The following Classification spectrum was provided:
Obsdate: 2026-05-07 00:00:00
Instrument: KCWI
Telescope: Keck II 10m
