About this image

Part 5 of a series of animations, showing the evolution of the spectrum from 2023-09-25 to 20240108. The full series of animations can be viewed here.

I changed over to the lower resolution modified ALPY200 spectrograph during this sequence once the brightness dropped below 15.5. The higher resolution spectra in this animation have been filtered to match the lower resolution of ~45 Angstrom.

In this animation we see the emergence of strong "forbidden" lines of [O I] and [Ca II] as the supernova moves into the nebular phase.

Generated using ISIS software from 5 observations interpolated at 1 day intervals and animated at 10fps

The original spectra are available from the BAA spectroscopy database
