Dear Observers,

For the upcoming lunation, we have a few new/return binaries, plus a few
other targets needing more data as well as return "prime suspects".  
Enjoy.

This list of targets is also available on

Clear Skies,

3. Paired asteroids (errors <0.05 mag needed):

4. New targets

Note: The ephemerides were computed for 2010-09-08
      ^/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.
