During the ongoing All Sky Automated Survey for SuperNovae (ASAS-SN or "Assassin"), using data from the recently expanded quadruple 14-cm "Brutus" telescope in Haleakala, Hawaii, we discovered a new transient source, most likely a supernova:
Object RA (J2000) DEC (J2000) Disc. UT Date Disc. V mag
ASASSN-13do 14:30:09.83 +31:12:55.4 2013 Dec. 25.60 14.7
ASASSN-13do was discovered in images obtained 2013 UT Dec. 25.6 at V = 14.7 mag. The source is undetected (V > 17 mag) in images obtained UT Dec. 22 and earlier.
The transient is located approximately 0.4" S and 7.5" W of the strongly star-forming LIRG NGC 5653 (z=0.01188, d=53 Mpc from Virgo-infall corrected velocity via NED), which would give it an absolute V mag of -19.0 (m-M=33.62, A_V=0.039, Schlafly & Finkbeiner 2011) and a projected distance from the host galaxy of approximately 1.9 kpc. Follow-up observations are encouraged.
We thank LCOGT and its staff for their continued support of ASAS-SN.
