Research Abstract

A micro-satellite of the Japanese mission was successfully launched from Baikonur Cosmodrome in Kazakhstan on August 23, 2005. We can simultaneously observe spatial distribution and time variation of fine aurora emissions associated with auroral electron precipitation and ionospheric ion outflows with a full pitch-angle coverage and a high-time resolution. Our Reimei team has also started some collaborative observations with EISCAT, all-sky cameras, and SuperDARN. Almost every new moon interval, we have been achieving simultaneous observations with Reimei and the ground-based instruments.
