Special Notice #393: Correction to Special Notice #392 [ASASSN-14lp]

December 11, 2014: 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!

This AAVSO Special Notice was compiled by Elizabeth O. Waagen.

Special Notice #392: ASASSN-14lp = Type Ia Supernova in NGC 4666 (Virgo)

December 11, 2014: 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-14lp. ASASSN-14lp was not seen (<15.3 V) in poor-quality ASASSN images obtained on 2104 Dec. 08.35 UT.

Special Notice #250: Possible Type-Ia Supernova in M101

August 24, 2011: P. Nugent et al. report in ATel #3581 that a possible Type-Ia supernova has been discovered by the Palomar Transient Factory shortly after eruption in the galaxy M101 and has been designated "PTF11kly".  The object is currently at a magnitude of g=17.2, but may well rise by several magnitudes. The object is well placed within M101 for good photometry, and observations of this potential bright SNIa are strongly encouraged.

The (J2000) coordinates reported for the object are

    RA: 14:03:05.81 , Dec: +54:16:25.4
