behalf of a larger European collaboration:
"We have obtained images covering about 95% of the 100
sq. arcmin error box reported by Hurley et al. (GCN #672)
with the 2.56-m Nordic Optical Telescope (+ALFOSC, mosaic
of 5 pointings) on La Palma, and the 1.54-m Danish
Telescope (+DFOSC) at La Silla, as follows:
Telescope Date Filter/Exp FWHM
NOT 2000 May 20.17 UT (t+20h) R: 180-360 s 1.5"
DK-1.54m 2000 May 20.39 UT (t+25h) R: 4x240 s 1.7"
DK-1.54m 2000 May 25.37 UT (t+6d) R: 3x300 s 3.5"
Observations were hampered by moonlight. Using the photometry
provided by Henden (GCN #673), we obtain limiting magnitudes
of R~20.8 for the NOT, and R~21.0 for the DK-1.5m May 20
image.
The exposures have been compared internally, and with the
DSS-II (red) exposure. No candidate counterpart was found."
