     NEAR is already farther from the Earth than the Moon, so
further optical observations will be very difficult and are
unlikely.  But just in case someone wants to try, I have generated
topocentric ephemerides for some major Southern-Hemisphere cities
and will post finder charts for them in a couple of hours at IOTA's
Web sites,
http://www.sky.net/~robinson/iotandx.htm  and
http://www.anomalies.com/iota/splash.htm
The topocentric data are at 30-minute intervals during Jan. 24 and
25 U.T.  An abbreviated geocentric ephemeris is below.  The
magnitude has been adjusted to fit Spacewatch's 20th mag. estimate
at about 300,000 km when they observed NEAR after launch in 1996.
The departure phase angle is similarly unfavorable this time.

 The following is an ephemeris for NEAR
