AAVSO Special Notice #392
December 11, 2014

ASASSN-141p = Type Ia Supernova in NGC 4666 (Virgo)


T. W.-S. Holoien et al. announce in The Astronomer's Telegram
(ATel) #6795 (http://www.astronomerstelegram.org/?read=6795) the discovery of a transient in NGC 4666 at magnitude 14.3 V on 2014 December 9.61 UT. The discovery was made in the course of the All Sky Automated Survey for SuperNovae (ASASSN) search, and the object assigned the name ASASSN-141p. ASASSN-141p was not seen
(<15.3 V) in poor-quality ASASSN images obtained on 2104 Dec.
08.35 UT.

J. Thorstensen et al. announce in ATel #6801
(http://www.astronomerstelegram.org/?read=6801) that ASASSN-141p is a Type-Ia supernova a few days before maximum.

Observations are requested of this Type-Ia supernova.

Coordinates: RA 12:45:09.101 Dec. -00:27:32.49 (2000.0)

ASASSN-141p is located 12" from the center of NGC 4666. It is currently a pre-dawn target, but will become more favorably positioned as the outburst progresses.

A finder chart for ASASSN-141p with sequence may be created using the AAVSO Variable Star Plotter (VSX, http://www.aavso.org/vsp).

Please submit observations to the AAVSO International Database using the name ASASSN-141p. Once a supernova ID has been assigned by the Central Bureau for Astronomical Telegrams, please use that name.

Correction to Special Notice #392

Correction to Special Notice #392


In AAVSO Special Notice #392, the name of the supernova discovered in NGC 4666 was given as ASASSN-141p. It should have been ASASSN-14lp. That is to say, the text following the dash should be "fourteen ell pee" and not "fourteen one pee".

Please create charts and submit observations using the name ASASSN-14lp.

Sincere apologies for the error!
