During the ongoing All Sky Automated Survey for SuperNovae (ASAS-SN or "Assassin"), using data from the double 14-cm "Casius" telescope in CTIO, Chile, we discovered a likely supernova in NGC 2466

Object       RA (J2000)     DEC (J2000)      Disc. UT Date   Disc. V mag  
ASASSN-14dd  07:45:14.38   -71:24:14.04       2014 06 24.95    15.6 
ASASSN-14dd was discovered in images obtained 2014 UT June 24.95 at V~15.6. We do not detect this object (V>15.7) in images taken on 2014-06-19.94 and there is a deeper non-detection (V>16.6) on 2014-06-09.99.

ASASSN-14dd is approximately 25" from the center of NGC 2466, a luminous face-on spiral and host galaxy of SN 2003gh. Given NED luminosity distance for NGC 2466 of 75.4 Mpc, ASASSN-14dd has absolute magnitude of M_V = -19.2 (m-M = 34.39 mag, A_V=0.45). Follow-up observations, particularly spectroscopy, are encouraged.
