Lightcurve analysis of the asteroid 9021 Fagus observed at the Bulgarian National Astronomical Observatory Rozhen during two apparitions in 2013 and 2017 are presented . This asteroid was observed in 2013 accidentally in the field of view in which our long-term target asteroid 901 Brunsia was positioned . A search of the Asteroid Lightcurve Database ( Warner et al . 2009 ) did not find any previously reported results for the rotation period of 9021 Fagus . Unfortunately two nights observations in 2013 showed that the rotation period could be only approximately assumed . The observations during two neighbouring nights in 2017 March 20 and 21 revealed the period of 5.065 \pm 0.002 h with amplitude of 0.73 \pm 0.02 mag . Obtained lightcurves in combination with other observational techniques , as well as with data gathered from future space mission will contribute to the enlargement of the database for rotational characteristics of the asteroids .
