Marla - I just received the latest IAU Circular, which included many new orbits. These have been added to the orbit catalog. I don't know of any of them are ones you're working on. The following pairs have improved orbits: 005935.07-011130.5 00596-0111 A 1903AB 022010.42+294842.4 02202+2949 A 961 063432.03-111347.0 06345-1114 HO 234 193043.29+275734.9 19307+2758 MCA 55Aac 195327.68+240446.3 19535+2405 DJU 4 201504.77+374145.1 20151+3742 COU2416 211342.46+642415.1 21137+6424 H 1 48 235034.33-514218.5 23506-5142 SLR 14 The following pairs have orbits for the first time: 001509.80+272345.1 00152+2722 J 868 002054.61+105837.1 00209+1059 BU 1093 013430.71+780345.8 01345+7804 HDS 211 042547.49+180102.5 04258+1800 COU2682 071037.92+154314.2 07106+1543 J 703 080319.18+525044.1 08033+5251 HDS1149 162535.12-232649.6 16256-2327 H 2 19AB 220818.81+240925.1 22083+2409 HDS3145 233323.87+425046.4 23334+4251 HDS3356
