report:

"Following the detection of SGR-like behaviour from the
anomalous x-ray pulsar 1E 2259+586 by RXTE (GCN#1432),
we have observed the field with the auxiliary port camera
at the 4.2-m William Herschel Telescope at La Palma on
June 20, 02:53-03:35 UT.  We do not find optical emission
within the Chandra 0.6" radius error circle (Hulleman et
al. 2001, ApJ 563, L49) down to limiting magnitudes of
R = 24.8 and I = 20.0."
