I did this a couple days ago -- alas, it is not predicted to be in
any of the archived imagery from 644 Palomar or 608 Haleakala.  And
based on the present orbit, it is not expected to be in any of the
DSS2 or DSS digitized survey plates.  Of course as the orbit is
refined, it may come to intersect one of the old survey plates.  I
don't have any easy way of telling if it's close to being on one of
the plates or not.
