                  Paired asteroid, suspect binary.  Thorough collaboration
                  very needed.

                  A couple good quality full nights needed to establish.
(32800)   1990 QC19         17.1   32  142   0.3 -23  14.9 1.76 1.90   7opp
                  Binary suspect, more data needed to establish.

                  Binary suspect, more long sessions needed to nail down.

1. Returning binaries
(1717)    Arlon             14.7   10  169^  0.3 -53  12.3 1.91 2.20  21opp
                  D_2/D_1 ~ 0.6, P_orb = 117 h, P_1 = 5.15 h, P_2 = 18.23 h
(4029)    Bridges           16.5    3  172v  0.2 -55  12.9 2.19 2.53  16opp
                  D_2/D_1 = 0.27, P_orb = 16.32 h, P_1 = 3.57 h
(17260)   2000 JQ58         17.3   11  155^  0.2 -50  14.2 1.80 2.20  11opp
                  D_2/D_1 = 0.26, P_orb = 14.75 h

2. Paired asteroids (errors <=0.03 mag needed):
(2110)    Moore-Sitterly    16.3   14  139^  0.1 -40  13.8 1.81 2.20  18opp
(10123)   Fideoja           15.8  -16  155v  0.1 -62  14.1 1.80 2.27  15opp
(10484)   Hecht             16.8   18  156^  0.2 -44  13.8 2.14 2.32  14opp

3. Member of a cluster, "mini-family" (errors <=0.05 mag needed):
(39991)   1998 HR37         16.9    0  171v  0.2 -57  14.2 2.05 2.44  10opp
                  
4. Returning "prime suspects", to be followed up on their 2nd (3rd, ...) apparitions
(2501)    Lohja             16.4   15  146^  0.2 -43  12.1 1.95 2.42  29opp 12.08      3.8084          0.35  3
                  Data with errors <0.02 mag only are going to be useful.

5. New targets

Note: The ephemerides were computed for 2011-09-27
      ^/v means that the value increases/decreases by more than
      0.05 mag/day (for V) or by more than 0.5 deg/day for Dec and Elong.
      The rate of apparent motion (Mot) is in deg/day.
      Bga is the galactic latitude.
