It is known to exhibit a strong differential reddening caused by several galactic interstellar clouds in its line of sight. Based on two optical observation runs made in 2006 within and separated by a 6-month interval, we intend to detect the photometric variations (colors and magnitudes) of stars in NGC 4833 due to the varying interstellar reddening. %G English %L hal-02004083 %U https://hal.science/hal-02004083 %~ IN2P3 %~ CNRS %~ LUPM %~ UNIV-MONTPELLIER %~ LUPM_AS %~ UM-2015-2021
