We present the results of photometric observations of six Transneptunian objects and three Centaurs , estimations of their rotational periods and corresponding amplitudes . For six of them we present also lower limits of density values . All observations were made using 3.6-m TNG telescope ( La Palma , Spain ) . For four objects – ( 148975 ) 2001 XA255 , ( 281371 ) 2008 FC76 , ( 315898 ) 2008 QD4 , and 2008 CT190 – the estimation of short-term variability was made for the first time . We confirm rotation period values for two objects : ( 55636 ) 2002 TX300 and ( 202421 ) 2005 UQ513 , and improve the precision of previously reported rotational period values for other three – ( 120178 ) 2003 OP32 , ( 145452 ) 2005 RN43 , ( 444030 ) 2004 NT33 – by using both our and literature data . We also discuss here that small distant bodies , similarly to asteroids in the Main belt , tend to have double-peaked rotational periods caused by the elongated shape rather than surface albedo variations .
