"Further analysis of previously reported observations 
(GCN #651) of the BeppoSAX WFC localization of GRB 000424 
(Piro, GCN #644) using a sensitive image subtraction technique 
sets a 3-sigma limit of R > 22.8 on April 26.15 UT for any 
fading optical transient in the error circle. Magnitudes 
reported here are referenced to USNO-A2.0 catalog stars nearby."
