Observations of the optical counterpart to XTE J1650-500 with
the Magellan 1 telescope find it fainter than expected based on
reports of it's possible detection on the DDS2 red (Groot etal IAUC
7708 ) and blue (Castro-Tirado etal IAUC 7707 ) plates. The
observations were made with the Sackler MagIC CCD camera in
non-photometric conditions on 03 Aug 2002, but allow us to estimate
R~22 (at 04:06 UT) and V~24 at (04:12 UT). We note the presence of a
brighter star ~1.5 arcsec to the West of the counterpart with R~20 and
V~22, which is faintly detected on the DDS2 red plates and may be
blended and confused with the counterpart on the plates. An I-band
image of the field as seen from Magellan 1 on 02 Aug 2002 may be found
