H. Pedersen, J. Hjorth, B. L. Jensen (Copenhagen),
A. O. Jaunsen (Oslo), and S. Holland (Aarhus) report on behalf
of a larger collaboration:
"We have re-inspected our optical (R-band) images of GRB 990506
(GCN #342) obtained on 6.96 May 1999 and 7.91 May 1999 UT.
We find no convincing evidence for any stellar or extended
object at the position of the proposed radio transient (GCN #350),
neither in the sum image, nor in subsets. For the first night,
we estimate a limiting magnitude of R > 23.5 (for point sources).
Our images are available upon request."
