wow the three-peaked H alpha and beta features are interesting. Three blobs of ejecta (two towards us, one away)?
And yes it is still raining here.

I took a spectra last night with my LISA R~1500. The weather is very poor at present so follow up spectra is a bit hit and miss.
Very wide emissions at over 4000 km/s

Re: Recurrent nova U Sco in eruption
the rain stopped and the clouds parted for a little while, so I got set up and managed 1x1200seconds.
could someone please post a link for where to upload in the database?

Re: Recurrent nova U Sco in eruption
Adding another night, here is a comparison of flux calibrated spectra over three nights as the V magnitude dropped from 7.957 +/- 0.072 to 10.267+/- 0.025 taken with a LISA and processed using ISIS.
