Abstract : The COPEX attention was focused on the details of the early stages in the development of ionospheric (F-region) instabilities that precede the growth of equatorial bubbles. We continued our work on ground VLF station monitoring with the RPI/IMAGE instrument. We carried out RPI measurements using specifically designed operational modes with lower receiver gains. In the past year, several Radiation Belt Remediation (RBR) studies were done and many of them remain active. The results of two HAARP heating experiments with the digisonde at Gakona, Alaska are described. Additionally, we discuss work done in several areas. We introduced a new Java-based Drift software package for the digisonde drift data analysis and visualization. DISS Support for the Digisonde Network continued. The CAL/VAL, project which involved the establishment of a substantial database from a global network of digisondes, is described. Product and the improvements offered by ARIST 4.5 are discussed.
