There is a potential bright nova in Carina.
ASAS-SN data are saturated and they only provided an approximate position so both astrometry (to identify the progenitor) and photometry are encouraged.
Report it as ASASSN-18fv.

I also confirm this nova suspect, although not as bright as Rod. Observations are in the AID. There are some problematic comparison stars that observers need to be wary of in the immediate vicinity of the nova suspect.
