We have investigated the global features of interplanetary (IP) disturbances associated with 27-28 May coronal mass ejection
(CME) events using interplanetary scintillation (IPS) measurements of the Solar-Terrestrial Environment Laboratory (STEL).
Our IPS data taken between 2003 May 28 22h UT and May 29 7h UT showed a set of complex feature of IP disturbances, and most
of them are regarded as IP consequences of two full-halo CMEs which occurred in association with the X1.3/2B flare on May 27
23:07 UT and the X3.3 flare on May 28 00:27 UT. Some components of the IP disturbances were discriminated from the IPS data
by making the model fitting analysis iteratively. One of the components was an Earth-directed one, which appears to
correspond to the IP shock observed by ACE on May 29 18:30 UT. Other components were obliquely propagating ones, which either
preceded or followed the Earth-directed one. The global features deduced here are generally in agreement with heliospheric
reconstructions made from Solar Mass Ejection Imager (SMEI) measurements.
