ASASSN-16FV: NUCLEAR TRANSIENT IN IC 4705 (=AT 2016CQZ)

J. Brimacombe, Coral Towers Observatory et. al. report on ATEL 9123
that during ASAS-SN and using data from the quadruple 14-cm "Cassius"
telescope in Cerro Tololo, Chile, they discovered a nuclear transient in the
galaxy IC 4705. 

It was discovered in images obtained on UT 2016 June 6.28UT at V~15.6 mag.
It was also detected in images obtained on 
2016 June 07.26 (V~15.2)but not on 2016 May 28.33 and before to mag 17.1. 

www.astronomy.ohio-state.edu/~assassin/followup/asassn-16fv.png shows the
archival DSS image of the host (left) and the J. Brimacombe confirmation
image (right). The red circle has a radius of 5" and is centred on the
position of the transient in the J. Brimacombe image. 

The position of ASASSN-16fv is approximately 0.6" South and 0.6" East from
the centre of IC 4705 (z=0.011972, d=49.7 Mpc, via NED), giving an absolute
V-band magnitude of approximately -18.1 (m-M=33.46, A_V=0.272).
