Dear Colleagues,

The BinAstPhotSurvey went extremely well in the past lunation.
Your work on a number of new targets brought good data for 
nearly 20 objects (some of them need to be finished with
more data in the next lunation).  The high productivity was
mostly a combination of longer nights and good weather
in September.  I don't expect that we will keep the same 
pace during following lunations, but chances are good that
the basic survey phase (with the planned sample size of 200)
will be completed during first couple months of the next year!
If so, it will be sooner than I expected.  No problem, however,
as I plan be able to turn to working on simulations of the 
Survey since mid-February, as my other committments should be
completed by then (and I don't intend to allow myself to get
so overcommitted in the next year as I am in this year so far).

There is still a number of worked targets on the binast-webtool,
so I don't propose new targets at this time.
The most important target is the new binary (6244) Okamoto, for which
a few good long sessions with errors 0.01 mag or better are needed.
Some of you have your own targets in works, so unless you can work
Okamoto on a given night, completing the worked targets might be 
your next priority.  For the binary (2754) Efimov, monitoring an evolution 
of its mutual events with changing geometry is needed.  

This list of targets is also available on

Clear Skies,

Petr Pravec

                     Two nights from Skalnate Pleso show a very low 
                     amplitude.  A couple high quality (errors <0.01 mag) 
                     linked nights would be needed to reveal it.

                     Two good 5+ h long sessions should cover it well.

                     smaller, covering events as well as phases outside 
                     them are needed to complete the discovery phase for
                     this one.

1. New targets:

Note: The ephemerides were computed for 2006-10-22
      ^/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.
