Dear Observers,

The most urgent target in the upcoming lunation is the new binary (15700)
that requires a concentrated work so that its P_orb is established.
Then there are a few other binaries as well as return "prime suspects"
and paired asteroids.
Enjoy.

Clear Skies,

4. New targets

Note: The ephemerides were computed for 2010-10-08
      ^/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.
