We obtained optical spectra of V5583 Sgr on 2009 Sepetember 15. Blended lines around 5000A (FeII + [O III] ?) slightly developed in recent two weeks.

[] V1280 Sco : Optical spectrum

f:id:kanataobslog:20090921125929p:image

We obtained an optical spectrum of V1280 Sco on 2009 September 15. The spectrum still shows a strong continum emission. Balmer and FeII emissions were also strong. No nebular or coronal lines were seen in our spectra. These results imply that outflows continue from a WD surface and optically thick layers might be formed even at ~1000 days after the explosion.
