A search for 3 TeV Gamma-ray bursts (GRBs) coincidentwith the BASTE experimentwas done
by using the data of the Tibet HD air shower array. 15 GRBs in the 4B BASTE catalog were searched,
whichwere obtained in March, 1998, and within the effective viewing sky of the Tibet HD array. The so-
called cluster method was adopted in the analysis. No convincing signal was detected fromthe direction the
BASTE GRBs. The result supports the cosmological model of gamma-ray bursts.
