94032021-04-16 11:18:57crangusC. Angus, C. Rojas-Bravo, L. DeMarchi, W. Jacobson-GalanYSESN0.0234YSESpectrum taken with ALFOSC/NOT in gr4 on 15/04/2021. Signatures of flash ionisation are seen within the spectrum (a blue continuum with a blended He II/N III feature and C IV emission). The narrow Balmer lines within the spectrum are consistent with the host galaxy. SN2021jtt rose 2.3 magnitudes over 3 days from last non-detection, suggesting that the transient was < 3 days from explosion at the time of observation.2021TNSCR1233....1A
