Dear Colleagues,

I am back from the workshop, catching up with things (and recovering 
from the jet lag).  I have looked at new data (processed in part by 
Peter K. when I was away).  It appears that we have several worked 
targets where a collaboration is urgently needed.  I give them below
in an order of priority; first objects need collaboration most.  Please
work them after the Moon is away rather then starting new targets.

This list of targets is also available on

Clear Skies,

Petr Pravec

Prime collaboration targets:
(32008)   2000 HM53         15.9   -3  153v  0.2 -33  14.1 1.77 2.19   7opp
                     Binary, can be well established soon after the full
                     moon with a few good nights.  See the binast-webtool.
(10208)   1997 QN1          16.4   -7  150v  0.1 -32  14.6 1.79 2.24   7opp
                     Binary suspect.  Collaboration needed (see the binast-
                     webtool).
(16635)   1993 QO           15.5   19  153   0.4 -32  13.9 1.65 2.30   7opp
                     Short period, low amplitude, possible deviations 
                     suggesting binarity.  Collaboration needed (see the
                     binast-webtool).

Targets where more data, usefully or preferrably from other than starting 
station are needed:
(3936)    Elst              15.7    3  170   0.2 -47  13.0 2.12 2.43  14opp
                     Worked from S. Pleso, but they would appreciate a help
                     with nailing it down.
(10443)   van der Pol       16.2   -5  150v  0.2 -31  13.7 1.95 2.27  10opp
                     A few good nights should establish this one.  (Short
                     period, low amplitude.)
(7870)    1987 UP2          14.8   -5  163v  0.2 -42  13.3 1.63 2.24   9opp
                     Low amplitude (~0.08 mag), but a period is not too
                     long.  It is a U=1 case so far, a few good, long, 
                     well sampled sessions with errors of 0.01 mag would 
                     be needed to establish this one.
(10313)   Vanessa-Mae       15.7   -8  156v  0.2 -37  14.0 1.79 2.26   8opp
                     Low amplitude (~0.09 mag), period unclear but maybe
                     not too long.  It is a U=1 case so far, a few good, 
                     long sessions with errors of 0.01 mag would 
                     be needed to establish this one.

Targets under control, no collaboration needed:

                     Slow rotator.  Under control by David Higgins.
(2896)    Preiss            14.3   -3  174^  0.3 -57  12.7 1.81 2.22  12opp
                     Slow(ish) rotator.  Under control by Don Pray.
(6265)    1985 TW3          15.8  -29  128v  0.1 -23  13.5 1.75 2.17  11opp
                     Binary.  Under control by David Higgins.
(9120)    1998 DR8          15.3    0  163v  0.2 -40  13.7 1.81 2.27  12opp
                     Slow(ish) rotator.  Under control by Don Pray.
                     
Note: The ephemerides were computed for 2007-09-07
      ^/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.
