Dear Observers,

Here is an updated list of targets.  

Fyi, I'll be on vacation during August 4-26, and Peter K. will be on vacation
during August 16-September 2.  I'm affraid that during the eleven days 
Aug 16-26 there will be no one here processing new observations, but 
I believe that you will muddle through :-)

This list of targets is also available at

Clear Skies,

Petr Pravec

4. New targets

Note: The ephemerides were computed for 2012-08-18
      ^/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.
