Dear Colleagues, For the Jan/Feb lunation, we have two binary suspects, 1293 Sonja and 7369 Gavrilin. They both will be observable by most of us (errors <=0.03 mag), so I encourage you to contribute to the effort of confirming/establishing their binary character. For two other binaries discovered recently, 3673 Levy and 7225 Huntress, more data would be useful. Of the other worked targets, a collaboration is needed for 72396, we need two full nights to establish it. Then there is one returning "prime suspect", 3657 Ermolova. Ok, though the two binary suspects and the other targets will probably keep us busy well through the lunation, I provide also new targets further below, for a case all worked targets reachable from your station on a given night are covered by someone else, or for a later part of the lunation where some worked targets may be done already. This list of targets is also available on http://www.asu.cas.cz/~asteroid/binastphotsurvey_listoftargets20080207.txt Clear Skies, Petr Pravec Object V Dec Elo Mot Bga H q a Arc 0.
