Amazing to have a hat trick of bright novae, and the latest such an anticipated event. The weather here in Somerset has been poor this last few weeks but in murky conditions I was able to capture RS Oph last night, just 20 minutes after Robin’s spectrum in the BAA spectroscopy database. There is good agreement between our two spectra, both captured with an Alpy 600. Compared to David’s spectrum from the previous night (higher resolution LISA spectrum), there has been a significant increase in the relative intensity of the emission lines but is this due mostly to a decline in brightness of the nova?
Cheers
Hugh
