Dear Observers,

There are a number of worked targets --several return binaries,
mini-family members, a YORP-detection object and a couple other targets--
as well as new returning binaries and paired asteroids.  Enjoy!

This list of targets is also available at

Clear Skies,

4. New targets

Note: The ephemerides were computed for 2012-02-22
      ^/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.
