An eruptive prominence happened on the east-northern limb of the Sun on March 7, 1991. It appeared in a relatively quiet region where any activity phenomena such as flare, filament and sunspot etc. was not found. The maximum height reachable of the prominence was 6.97×104km and its maximum length reached as 11.6×104km. The eruptive prominence might belong to the one of the middle-smaller scale according to its size in morphology. The course of the eruption exhibited some properties: ascending rapidly and descending slowly just like the process of the flare eruption. After the eruption, the most material in the prominence basically moved along a parabola under the action of magnetic force lines forming the arcade-like shape and keeping it till to the disappearance of the prominence. Before and after descending, a little matter came from the top part was ejected and divorced from the main body of the prominence and diffused into the interplanetary space.
