Dear Observers,

For the upcoming lunation, we have as many as five return binaries and 
a few other interesting targets for the BinAstPhotSurvey and the NEOSource
project.  Of very high importance is the NEA binary 1996 FG3 for which
just one event detection (possibly just one night) in this apparition could
give a unique model for detecting BYORP; it would be the first such case.
Then there are many other interesting targets for all of us :-)  Enjoy!

This list of targets is also available at

Clear Skies,

Petr Pravec

Note: The ephemerides were computed for 2011-12-25
      ^/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.
