Dear Observers,

Updated list of targets is below.  The currently most urgent target 
is the binary candidate (3951) Zichichi for which more data are needed to
nail down.

This list of targets is also available at

Clear Skies,

Petr Pravec

                  unique solution.

                  Binary suspect, more data needed to nail down.

1. Returning binaries
(2486)    Metsahovi         16.2  -14  133^  0.1  46  12.6 2.09 2.27  20opp
                  2-period case (no events seen previously),
                  P_1 = 4.45 h, P_2 = 2.64 h
(3073)    Kursk             16.8   -8  153^  0.2  55  13.7 1.94 2.24  18opp
                  D_2/D_1 = 0.25, P_orb = 44.96 h
(3982)    Kastel'           16.7  -12  151^  0.2  50  13.2 1.77 2.26  16opp
                  2-period case (no events seen in 2005),
                  P_1 = 8.49 h, P_2 = 5.84 h
(6244)    Okamoto           16.4    5  178   0.3  55  13.6 1.83 2.16  13opp
                  D_2/D_1 = 0.25, P_orb = 20.32 h

2. Paired asteroids (errors <=0.03 mag needed):
(11842)   Kap'bos           16.8   -9  155^  0.2  53  13.8 2.04 2.25  12opp
                  It is a "prime suspect", this pair primary has 
                  P_1 = 3.6858 h, A_1 = 0.13 and it may be binary itself.
                  See lightcurve of 2009, published in Pravec et al. 
                  (2010): http://www.asu.cas.cz/~asteroid/011842.png
                  Unfortunately, in this apparition the asteroid is almost
                  exactly diametrically opposite to its position in 2009,
                  so since no events were detected in 2009, a likelihood
                  that we will see some in this apparition is low.
                  
3. Returning "prime suspects", to be followed up on their 2nd (3rd, ...) apparitions

4. New targets

Note: The ephemerides were computed for 2011-03-05
      ^/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.
