Asteroid 37 Fides spins around its axel once in every 7,3 hours. In Taurus Hill Observatory we measured about five (5) hours from this one spin. The lightcurve below is a result of about 200 separate R -filter -pictures (60 sec. exposure in each picture). This measurements was made in 11.-12.1.2007 and the sky was clear and temperature was about - 8 celcius. The comparison stars that were used in this measurement were C1 GSC1931-446 and C2 GSC1931-860.
