About this image

Part 3 of a series of animations, showing the evolution of the spectrum from 2023-06-13 to 2023-07-19. (part 1, part 2)

This shows the growing broad P Cygni line from Hydrogen alpha and the emergence of other broad absorption lines from various metals. The end of the animation shows an overlay of SN 2003bn measured at the same epoch with lines identified (from Claudia P. Gutiérrez et al 2017 ApJ 850 89 fig 9)

Generated using ISIS software from 4 observations interpolated at 0.5 day intervals and animated at 10fps

The original spectra are available from the BAA spectroscopy database
