Princeton University report: ``Observations made on Dec 17 UT 
using the ARC 3.5-meter telescope at Apache Point Observatory show 
that the optical transient reported by Halpern et al. in IAUC 6788 
has continued to fade.  We measure on Dec 17.51 UT a magnitude 
R=24.4+-0.5 for the OT, from six 10 min exposures taken by Corson, 
Gilmore and Wyse.  Calibration of photometry has been done using 
Landolt standard star 104239."

This message is quotable in publications.
