Dear Colleagues,

Great work recently, several targets have been finished, so it is a time 
to update the list of targets now.  One remaining worked target 1996 FG3 
is very important; it is a returning NEA binary and we need to observe it
to refine its orbital model as well as to support planned observations 
with other instruments (IRTF, Arecibo, HST).  As usual, good long sessions
with errors not greater than 0.03 mag are needed.  With just a bit of
concentrated effort, it may be done fairly quickly, however.  Then there
are two new returning binaries (or serious suspect).  And then there are 
of course several new targets suitable for the Survey.

Enjoy.

Clear Skies,

Petr Pravec

Note: The ephemerides were computed for 2009-04-25
      ^/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.
