Plasma bubble limb imaging observation from the International Space Station
Abstract
Vertical structures of plasma bubble was studied with airglow images taken from the International Space Station(ISS). A lot of airglow imaging observations from ground and satellites have revealed horizontal structures of plasma bubbles. However, plasma bubble dynamics has not been completely understood due to lack of knowledge about its vertical structure. Recently, it was found that airglow vertical structures were captured in the pictures taken by digital single reflex camera from the ISS. 630 nm and 557.7 nm airglow emission from the F region ionosphere can be seen in the images and some plasma bubble structures are identified. Comparing the city light position in the pictures and city position on map, we determined exact position and attitude of ISS at the time when pictures were taken. After these calibration, exact location and size of airglow structures were determined. It was found as a result that the airglow structures are field-aligned and the spatial scale of the structures are about 50km.
