Supernova 2001el in NGC 1448
Abstract
Liebert A. G. Monard, situated 40 km east of Pretoria, South Africa, reports his visual discovery of an apparent supernova (mag 14.5) on Sept. 17.064 UT. Using a 0.32-m reflector, Monard estimated the new object to be about 9" west and 15" north of the center of NGC 1448, and he observed SN 2001el again at m_v = 14.3 on Sept. 17.930; nothing was noticed at this location to mag 14.6 on Aug. 25.96. G. Bock, Edens Landing, Queensland, estimates mag about 13.2 for SN 2001el from an unfiltered CCD image taken on Sept. 18.61. A. Wassilieff, Palmerston North, New Zealand, reports the following position for SN 2001el from an unfiltered CCD image taken through clouds on Sept. 18.636 (when the new object appeared at mag 13.9) with a 0.38-m reflector: R.A. = 3h44m30s.60, Decl. = -44o38'23".4 (equinox 2000.0), which is 14" west and 20" north of the nucleus of NGC 1448. J. Biggs provides the following position end figures for SN 2001el from three unfiltered CCD images obtained on Sept. 19.62 with the 0.25-m Mike Candy Telescope at Perth Observatory: 30s.57 +/- 0s.02, 23".7 +/- 0".3 (USNO-A2.0 reference stars), which is about 22" west and 19" north of the center of NGC 1448; the magnitude of the new star was R = 14.5 +/- 0.5. SN 1983S also appeared in NGC 1448 (cf. IAUC 3877).
