We observed the light curve of the asteroid 409 Aspasia first time in Taurus Hill Observatory (A95) at 14/15 of September in 2006 and measured about 2,3 h of its light curve. The rotational period of this 162 diameter asteroid is 9,020 h. We used fotometrical R-filter and each exposure time was 60 s. The fotometric analysis is done in AIP4Win software and the light curve in Peranso2.02 sofware. The observing wheather was very good, but half Moon was high in the nigthy sky and so backgroud light was disturbing. We used GSC1182-856 as a comparison star and GSC1182-318 as a check star. Observer: Veli-Pekka Hentunen.
