They are available at http://club.idecnet.com/~rvr/img/aug311.gif and http://club.idecnet.com/~rvr/img/aug232.gif ... The images aren't as good as aug271. The object, if there, is in the detection limit. Aug 23.2 UT, 15 min exp, Mv=15.0, Magnitude limit was 15.5 (aug232.gif) Aug 31.1 UT, 13 min exp, Mv=14.0, Magnitude limit was 14.5 (aug311.gif) Last night, Sep 1.1 UT, I take another shot of the area with 30 minutes of exposure (same instruments as lasts). There is nothing brigther than 16.5. Visually, I didn't see anything brighter than 14.8.
