Dear Observers,

Here is a new list of targets.  There are a few worked binaries, return
binaries as well as "prime suspect".  Enjoy.

This list of targets is also available at

Clear Skies,

0. Worked objects:
(1453)    Fennia            15.3   26  130v  0.3  54  12.7 1.84 1.90  24opp
                  Return binary, monitoring of events needed to establish 
                  unique solution.
(2815)    Soma              16.1    6  168v  0.3  68  12.6 1.86 2.23  19opp
                  New binary, see status on the binast-webtool.
(3951)    Zichichi          16.8   13  112v  0.2  27  12.8 1.93 2.34  13opp
                  Binary suspect, more data needed to nail down.
(5129)    Groom             15.1   -1  163^  0.3  58  12.4 2.17 2.38  16opp
                  Return "prime suspect", a couple more sessions needed.
(99913)   1997 CZ5          16.1  -18  113   0.3  10  13.4 1.38 2.29   9opp
                  Binary, monitoring useful.

1. Returning binaries
(2486)    Metsahovi         15.4  -15  166^  0.3  47  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             16.5   -4  169v  0.3  58  13.7 1.94 2.24  18opp
                  D_2/D_1 = 0.25, P_orb = 44.96 h
(3982)    Kastel'           16.2   -9  168v  0.3  52  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

2. Paired asteroids (errors <=0.03 mag needed):
(11842)   Kap'bos           16.6   -6  166v  0.2  54  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.

4. New targets

Note: The ephemerides were computed for 2011-04-04
      ^/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.
