摘要：
During the 21 August 2017 total solar eclipse the corona was observed through a narrowband filter centered at the Fe xiv green emission line at a cadence of 30 frames/s. A bright region on the east limb was observed to dim during the 2 m 35 s totality. Details of the temporal behavior of this region are reported. The likely association of the dimming with a coronal mass ejection (CME) in progress during the eclipse or the small sunspot group with coronal loops near the east limb is discussed.
