Dear Colleagues, There are two binaries that have been discovered a few weeks ago and follow-up observations would be useful for them. I assume that 1453 Fennia will be under control by Brian Warner (Brian, let us know if you need a help by other stations). 8116 Jeanperrin is still observable for a few hours in evening from stations that can work it at V~17; I will put an ephemeris to the binast-webtool. Of the other worked targets, the only one where a collaborative work is called for is (8335) for which David Higgins has found a period ~6 hr from his single night data, but it will be too faint for him to obtain good data in the December lunation, therefore two full nights from another station able to work it with errors <=0.03 mag will be needed. New proposed targets are listed further below. With the ecliptic at high declinations in December, there are few suitable targets for Australian observers; David, you will see that I have found only three suitable pre- or in-opposition targets at declinations between -15 and +10 deg. It is a situation similar to what we northern hemisphere observers encounter in June. This list of targets is also available on http://www.asu.cas.cz/~asteroid/binastphotsurvey_listoftargets20071210.txt Clear Skies, Petr Pravec Object V Dec Elo Mot Bga H q a Arc 0.
