I generated the ephemeris using the JPL site and this asteriod will be fading fast over the next week or so. Optimal time is right now at just under mag 10 ... within a week it will be moving to near mag 15!
To generate the ephemeris yourself with daily estimates for RA, Dec, mag etc, you can visit http://ssd.jpl.nasa.gov/cgi-bin/eph?sstr=111577&group=all&s_sb=Search&c_loc=500;Geocentric;0.,0.,0.,m&c_time=+20011212000000.000,+20011227000000.000,0,1,d,,C&c_quan=0108c0101,JHA,,0 ... I do not remember if this is the same link as that posted by Ulrich or not.

Dear List,For any interested in sample photos, exposures and equipment used by others in capturing this asteroid, you can point your browsers to http://www.spaceweather.com/asteroids/1998wt24_movies.html for a nice set of images!!!

Marie,With an aperture of 8", you have a limiting visual magnitude of about 14.2 under excellent skies and if you have good optics. Similarly, with a focal lengh of 1000 mm and also with good optics and excellent skies, you have a limiting photographic magnitude of about 17.
I suggest you try and locate magnitude estimates for the asteriod of interest to see where it falls in relation to the figures (14.2, 17) above. I checked Pasachoff (Petersen Field Guide: Stars and Planets) and the 15 brightest satellites have a magnitude of 8.3 or better.
