In this paper , we report our multiwavelength observations of the simultaneous transverse and longitudinal oscillations in a quiescent prominence . The prominence was observed by the Global Oscillation Network Group and by the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory ( SDO ) on 2015 June 29 . A GOES C2.4 flare took place in NOAA active region 12373 , which was associated with a pair of short ribbons and a remote ribbon . During the impulsive phase of the flare , a coronal jet spurted out of the primary flare site and propagated in the northwest direction at an apparent speed of \sim 224 km s ^ { -1 } . Part of the jet stopped near the remote ribbon . The remaining part continued moving forward before stopping to the east of prominence . Once the jet encountered the prominence , it pushed the prominence to oscillate periodically . The transverse oscillation of the eastern part ( EP ) of prominence can be divided into two phases . In phase I , the initial amplitude , velocity , period , and damping timescale are \sim 4.5 Mm , \sim 20 km s ^ { -1 } , \sim 25 minutes , and \sim 7.5 hr , respectively . The oscillation lasted for two cycles . In phase II , the initial amplitude increases to \sim 11.3 Mm while the initial velocity halves to \sim 10 km s ^ { -1 } . The period increases by a factor of \sim 3.5 . With a damping timescale of \sim 4.4 hr , the oscillation lasted for about three cycles . The western part ( WP ) of prominence also experienced transverse oscillation . The initial amplitude is only \sim 2 Mm and the velocity is less than 10 km s ^ { -1 } . The period ( \sim 27 minutes ) is slightly longer than that of EP in phase I . The oscillation lasted for about four cycles with the shortest damping timescale ( \sim 1.7 hr ) . To the east of prominence , a handful of horizontal threads experienced longitudinal oscillation . The initial amplitude , velocity , period , and damping timescale are \sim 52 Mm , \sim 50 km s ^ { -1 } , \sim 99 minutes , and 2.5 hr , respectively . To our knowledge , this is the first report of simultaneous transverse and longitudinal prominence oscillations triggered by a coronal jet .
