During the ongoing All Sky Automated Survey for SuperNovae (ASAS-SN or "Assassin"), using data from the recently commissioned double 14-cm "Cassius" telescope in Cerro Tololo, Chile, we discovered a new transient source, most likely associated with the known active galaxy PKS 1716-771

 
Object       RA (J2000)   DEC (J2000)      Disc. UT Date   Disc. V mag 
ASASSN-14ct  17:23:51.3   -77:13:49.9      2014-06-19.17      16.1 

The ASASSN-14ct outburst was discovered in images obtained 2014-06-19.17 UT at V~16.0 mag. We also detect the object in images obtained on 2014-06-18.08 (V~16.7 mag) and 2014-06-20.17 (V~16.0 mag). We do not detect this object in images obtained on 2014-06-13.15 (V>16.0 mag) and 2014-06-09.15 (V>16.8 mag).

PKS 1716-771 has a USNO B2 magnitude of 19.71. PKS 1716-771 is associated with object J1725.1-7714 in the Second Fermi Gamma-ray LAT Catalog. Finally, J1725.1-7714 was noted to show variability in WISE and was classified as an active galaxy with undetermined type (Massaro et al. 2013). Follow-up observations are encouraged.
