  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 $0.73\pm0.02$ 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.
