The ASAS-SN team has posted a bright transient on the TNS:
ASASSN-25cm = AT 2025nlr 15:08:03.274 -40:08:29.58 g=8.7
https://www.wis-tns.org/object/2025nlr
with the following comment: "Very bright, young transient, possibly a Galactic Nova; photometry likely uncertain as the object is close to/above saturation limit".
The extinction in this direction is relatively low A(V) = 0.345, so a typical classical nova peaking at absolute magnitude M_V= -7.0 at 8 kpc distance would rise to V=7.9.
Confirmation imaging, astrometry, filter photometry and classification spectroscopy are all highly desirable.
