Veli-Pekka Hentunen and Markku Nissinen measured the lightcurve of the asteroid 173 Ino in 8.-9.4.2007 at Taurus Hill Observatory. The variation in light intensity was very small, only 0.06 magnitudes. Despite that the lightcurve turned out to be very good. The weather was quite gold, -6 celcius, and clear. Veli-Pekka and Markku used 150 sec. exposures and photometric R -filter for each measurement. The comparison stars were GSC0868-0691 (C1), GSC0868-0296 (C2) and GSC0868-0340 (C3). Reason for three comparison stars was the pier-flip of the mount.
