Unfortunately it is already too faint (<20.1G) but this object looks interesting:

Zoom in the Gaia light curve.
Even when the Gaia team wrote "Gaia source declines by ~2 mag over 12 days", there was no previous Gaia star there.
A nova or a supernova? No host or progenitor is seen.
The extremely clean light curve casts some doubts about it though.
Anyone able to get observations?
The object is at 14 48 26.86 -63 48 15.7 (J2000.0) in Circinus.
Beware of a 19th mag. star 3" to the NNW.
Cheers,
Sebastian
