Dear Colleagues,

An updated list of targets is below.  There are three worked return 
binaries and two new return binaries, they are top priority targets,
especially for northern hempishere stations.  Southern hemisphere stations
may work the return NEA binary (35107) 1991 VH, or, if it is not workable,
new targets from the list below.

Enjoy.

This list of targets is also available on

Clear Skies,

Petr Pravec

Note: The ephemerides were computed for 2009-01-26
      ^/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.
