Scientific paper

As part of a long-term investigation of halo-like coronal mass ejections (CMEs) well observed in white light by the SOHO LASCO coronagraphs, we report on a study comparing our catalog of parameters and solar and solar wind associations of halo CMEs with interplanetary disturbances observed with the interplanetary scintillation (IPS) radio array of STE Lab in Japan. We have cataloged over 100 full halo CMEs observed by LASCO from 1996 through 2000. This period covers the first half of solar cycle 23 from activity minimum to maximum. Although the STE Lab observations are limited during each year, nearly all of these CMEs occurring during STE Lab observations were associated with IPS disturbances within a day or so following the halo CME onset time. We will present a summary of these comparisons, and will discuss how the combined data sets can be used to determine key parameters of the 3D shape, structure and propagation of ICMEs. At STE Lab a program is used to find best-fit parameters automatically by matching model calculations to the observed IPS g-value (proportional to plasma density) data. At UCSD a tomographic program is used to reconstruct 3D views of ICMEs using the IPS data in a reconstruction technique based on solar rotation and outward solar wind motion. This work is also pertinent for observations that will be available from the Solar Mass Ejection Imager (SMEI) experiment to be launched next year and, later, from the NASA STEREO mission.
