摘要：
During the 21 August 2017 total solar eclipse the corona was observed through a narrowband filter centered at the Fexiv green emission line at a cadence of 30 frames/s. Abright region on the east limb was observed to dim during the 2m 35s 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.
