Dear Colleagues,

A new list of targets is below.  There are three worked binaries (or 
binary suspects) that need to be worked intensively: (1717) Arlon, 
(4935) Maslachkova, and (17260) 2000 JQ58.  The returing binary 
(9617) Grahamchapman should be workable for some of us able to reach 
a V=17 object with errors <0.03 mag.  The two paired asteroids 
(10484) Hecht and (106700) 2000 WX167 are fainter than our usual 
targets, but since we don't need so accurate data for them (just 
resolving their periods will be enough), some of us could work them 
as well.

Most of the targets are for northern hemisphere observers.  Southern 
hemisphere observers can work 4935 and 34155, and Julian maybe also 9617
(if the problem with his main scope is fixed), but if you run out of
the targets, let me know and I will provide new targets around the 
celestial equator.

Enjoy.

                        More observations to cover full P_orb is needed to 
                        reveal whether there occur events in the current 
                        geometry.

                        Observations for the return NEA binary from the 
                        southern hemispehre would be useful.

Note: The ephemerides were computed for 2008-11-28
      ^/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.
