The BeppoSAX Gamma Ray Burst Monitor (GRBM) and the Wide Field Camera
(WFC) unit 2 observed the GRB 010518 on May 18.280046 UT. The burst, that
was very faint and detected only by ground trigger logic, required a
careful off-line analysis.
The event detected by the GRBM shows an irregular single pulse profile
with a time duration of 25 s and a peak count rate of 210+- 40 c/s
corresponding to (1.3 +- 0.3)x10^-7 erg/cm^2 s in the 40-700 keV energy
band. In the WFC, the duration is about 30 s and the peak flux
is 0.7 Crab (2-26 keV). The centroid position of the X-ray counterpart
from the WFC image is R.A. = 10h46m43.7s, Dec = -57d47'36.7" (equinox
2000.0) with an error radius of 5'.
