Alert Notice 477: Supernova 2013E in IC 2532 = PSN J10000552-3414013

January 9, 2013

Event: Supernova 2013E in IC 2532 = PSN J10000552-3414013

Discovered by: Stuart Parker (Canterbury, New Zealand)

Discovery Date: 2013 Jan. 4.58 UT

Discovery Magnitude: red mag 14.8 on a 30-s unfiltered CCD image taken with a 30-cm Astro-Tech AT12RC Ritchey-Chretien astrograph (+ ST10 camera) at his Parkdale Observatory in the course of the Backyard Observatory Supernova Search (BOSS)

Coordinates: R.A. 10 00 05 .52  Decl. -34 14 01.3  (2000.0)
2" east and 19" south of the nucleus of IC 2532

Spectra: Spectroscopy obtained 2013 Jan. 6.16 UT with the 2.5-m du Pont telescope (+ WFCCD) at Las Campanas Observatory (LCO) by the Carnegie Supernova Project and reported by N. Morrell, E. Y. Hsiao, C. Contreras, and M. Phillips (LCO) indicates that SN 2013E is a type-Ia supernova several days before maximum brightness.

Charts: SN 2013E has been submitted to VSX. Once it is approved, finder charts for SN 2013E may be plotted using the AAVSO Variable Star Plotter (VSP) at

Reporting Observations: Please report all observations to the AAVSO International Database as SN 2013E.
