Congratulations, Alfredo!
This should be the third recorded eruption, which I had expected
for about 2018 March. Previous eruptions occurred on 1962 June 2
and 1990 April 27.
In recent months I observed V3890 Sgr on almost every night
(weather and moonlight permitting). Unfortunately tonight the
sky has been overcast here, and the two previous evenings it
was too cloudy or hazy low above my southern horizon.

Confirmation, spectroscopy, and multiband photometry are
urgently required.
