This movie shows a movie of an ejection event on the east limb of the
Sun as seen by the Nobeyama radioheliograph in Japan with an image every
1 minute. This event has been analyzed by N. Gopalswamy ("New
Perspectives on Solar Prominences", IAU Coll. 167, ASP 150, p 358). The time is
shown in the upper left corner of each panel and the maximum brightness
temperature of the off-limb material is shown in the upper right corner.
The material in the ejection is presumably filament or prominence
material, which sits elevated in the corona at a temperature of
typically several thousand degrees until the event. Since the peak
brightness temperature in the corona reaches 20000 K, the material must
be heated as it rises. The ejected material can be traced to a height of
over 600000 km, or almost a solar radius. The initial speed is about
250 km per second. The figure at the right shows the change in distance
from its launching place of the leading edge of the ejection as a
function of time.
