Abstract: The observations of a limb prominence (N 26; E 90) were carried out with the help of a Peltier cooled CCD system. In the beginning the prominence was observed as quiescent prominence with compact helical structure. Rise, detwisting and stretching of the helical structure near the top portion of the prominence was noticed at first which later on changed into a funnel shape depicting many bright knots. Then the eruption of the prominence occured. During eruption, oscillations in velocity (maximum observed velocity 500 km per second) have been noticed. The prominence had remained perceivable upto a height of about 4x10 to the power 5 km.
