H alpha is still prominent, possibly even brighter. It needs someone cleverer than me to do a flux calibrated spectrum. I’ve attached a plot of three spectra taken over the last three weeks to show the changes. This object continues to fascinate me. Any interpretation of what we are seeing would be welcome.
