(U of Amsterdam and U of Alabama in Huntsville) report: "Comparison of
red band images of the error box of GRB 980425 (Soffitta et al. 1998; 
IAUC 6884) taken at the 50in telescope at the Australian National
University's Mt. Stromlo Observatory on April 26.63 UT (1800s) and April
28.68 UT (1800s) shows no variation > 0.2 mag down to about 21 mag at 
the location of the transient BeppoSAX NFI X-ray source 1SAXJ1935.3-5252
(Pian et al. 1998; GCN #61)."

This work is based partly upon images obtained by the MACHO Project
with the 50in telecope at the Australian National University's Mt. Stromlo 
Observatory.
