>> visual observation? :)) [Yes I know it is very, very, very faint!:)] Just had a look at the longer-term ephemeris: (146268) won't be getting any brighter than V mag 19 for the coming decade. Kinda disappointing in that respect, but on the other hand it's an indication of the state of amateur asteroid observation that an object this faint is observed at all, much less discovered and followed-up well enough to be numbered. \Brian -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
