Photometric Observations of 596 Scheila, 1990 BG, 1990 TG1, 1999 CU3, 2000 DM8, 2001 PT9, 2001 SN263, 2002 NP1, 2002 JP9, 2003 UV11, 2006 AL8, 2008 SR1, 2009 BH81, 2009 QC, P/2010 A2 (LINEAR), 2010 JK33, 2010 LY63, 2010 RF12, 2010 UD, P/2010 R2 (La Sagra), 2010 YS, 2011 AN16, and 2011 EZ78

Twenty-three solar system minor bodies were measured photometrically between 2005 February and 2011 July using robotic telescopes in North America, Europe, and Australia. From the data obtained we determine for these objects their basic physical proprieties, such as Johnson- Cousins BVRI colors, H-G parameters, diameters, and a Tholen taxonomic classification. We found that 70% of our near-Earth asteroid sample belong to S-, Q-, X-, and C-complexes; 2009 BH81 may be a candidate to a new A type asteroid; 2010 RF12 is an S-type and it has absolute magnitude H = 28.46 ± 0.05, G = 0.31 ± 0.06 and D = 6 ± 1 m; the possible dust envelope around (596) Scheila and P/2010 A2 have similar colors.
