We report on BVI CCD photometry of a field centered
in the region of the open cluster NGC 1883 down to V=21.
This cluster has never been studied insofar, and we provide
for the first time estimates of its fundamental parameters,
namely radial extent, age, distance and reddening.
We find that the cluster has a radius of about 2.5 arcmin,
and shows signatures of dynamical relaxation. NGC 1883
is located in the anti-center direction, and exhibits a reddening
in the range E(B-V)= 0.23-0.35, depending on the metal
abundance. It turns out to be of intermediate-age
(1 billion years old), and quite distant for an open cluster.
In fact it is located 4.8 kpc from the Sun, and more than 13 kpc
from the Galactic center. This results makes NGC 1883
one of the most peripheral old open clusters, with
important consequences for the trend of the metallicity
with distance in the outer Galactic disk.
