NED Abstract

Reproduced by permission
2002IAUC.7800C...1M Circular No. 7800 Central Bureau for Astronomical Telegrams INTERNATIONAL ASTRONOMICAL UNION SUPERNOVA 2002E IN NGC 4129 Matheson et al. also write that a spectrum of SN 2002E (cf. IAUC 7797), obtained by Berlind as above on Jan. 19.51 UT, shows it to be a type-II supernova past maximum: "Adopting the NED recession velocity of 1174 km/s for the host galaxy, the expansion velocity derived from the minimum of the H-beta line is 1300 km/s. The spectrum shows a relatively flat continuum (strongly contaminated by light from the host galaxy) with P-Cyg lines of hydrogen, but with weak absorption troughs. In addition, lines of [Ca II] (729.1, 732.4 nm) are present, indicating the beginning of the transition to the nebular phase. Other indicators of the nebular phase, such as the forbidden lines of oxygen, are not obviously apparent." 2002 January 22 (7800) Daniel W. E. Green
