Here are 6 spectra around that date from the BAA spectroscopy database (From David Boyd (2), Kevin Gurney, Hugh Allen, John Coffin and me)

https://britastro.org/specdb/data_graph.php?obs_id=9120%2C9031%2C9159%2C9035%2C9118%2C9039&multi=yes&mix_flux=yes&plot=Plot+up+to+20+Spectra

They all line up in wavelength precisely

Cheers
