摘要：
Morphological properties of the corona and coronal structures, and modifications occurring in a time span greater than 3 hours were investigated through image analysis of three successive color pictures obtained by the Multi-station International Coronal Experiment (MICE). The model of Saito and Akasofu (1987) for the general magnetic field of the Sun was a suitable framework for interpreting the observational results. Color-index images allowed a closer inspection of the relationships between rays and underlying chromospheric activity. Besides the chromospheric active centres, the rays exhibited clear morphological alterations. Suggestions are presented for future observational efforts searching for slight morphological changes and tiny fluctuations in brightness and color-indices.
