Dear Colleagues, The August and September lunations were pretty productive. In the first part of the upcoming lunation (late September-October), there are still a few targets that require more data, and there is also the returning binary (4029) Bridges that is just passing through the opposition. Then there are three "prime suspects", of which (3665) Fitzgerald may be particularly interesting for Julian :-) The returning binary (4029) Bridges has been discovered in April 2006 by Higgins et al. (CBET 507). Its basic parameters have been well estimated Ds/Dp= 0.24 +/-0.02 P1= 3.5746 +/-0.0001 h Porb= 16.31 +/-0.01 h A1= 0.20 mag http://www.asu.cas.cz/~asteroid/4029_all.png http://www.asu.cas.cz/~asteroid/4029_longpc.png http://www.asu.cas.cz/~asteroid/4029_longpc_contacts.png http://www.asu.cas.cz/~asteroid/4029_shortpc.png Fyi, Petr Scheirich has added a new small useful feature to the binast-webtool - now it is possible to write there head notes to individual targets. I believe it will be obvious to you how it works when you use it. It should be useful for a better information for observers on what data individual targets need and such.
