(NASA-MSFC/USRA) on behalf of a larger collaboration, report: "We
obtained I band images with the ESO NTT and the Wise Observatory 1-m
telescope that cover the RXTE error circle of GRB980703 (IAU
Circ. 6966, GCN #126). We find the following magnitudes for the
optical transient proposed by Frail et al. (GCN #128; see also GCN
#130 and GCN #131):
UT date I telescope
July 4.06 20.1 +/- 0.2 Wise 1-m
July 4.37 20.6 +/- 0.2 NTT
July 5.05 20.9 +/- 0.3 Wise 1-m
July 6.44 21.3 +/- 0.2 NTT
No other sources in the entire RXTE error circle are found to be
variable by more than 0.4 magnitude between the two NTT epochs down
to I=22.6.
