NED Abstract

2001IAUC.7721A...1F Circular No. 7721 Central Bureau for Astronomical Telegrams INTERNATIONAL ASTRONOMICAL UNION SUPERNOVA 2001dj IN NGC 180 A. V. Filippenko and R. Chornock, University of California at Berkeley, report: "Inspection of CCD spectra (range 330-1000 nm) obtained on Sept. 20 UT with the Shane 3-m reflector at Lick Observatory reveals that SN 2001dj (IAUC 7674) is indeed a supernova, contrary to the report on IAUC 7680. The bright star located 56".6 east and 3".8 north of the supernova has an early-F spectral type, so we suspect this is the star whose spectrum is described on IAUC 7680. The supernova is a peculiar type-II event in the nebular phase, with strong, broad H-alpha emission having an asymmetric profile (the line peaks at -5000 km/s, after removal of the NED redshift); it also shows reasonably strong but somewhat narrower He I emission lines. He I emission lines at this phase are very rare in type-II supernovae." 2001 September 20 (7721) Daniel W. E. Green
