1·What's more, a decrease in sunspots doesn't necessarilymean a drop in other solar features such as prominences, which can produce aurora-triggering coronal mass ejections.
而且，太阳黑子减少并不一定意味着太阳的其它特征的减少，比如日珥——它能产生引起极光的日冕物质抛射。
2·Although very hot, prominences typically appear dark when viewed against the Sun, since they are slightly cooler than the surface.
虽然很热，日珥典型表现是在太阳的衬托下显得较暗，因为它们比太阳表面稍冷一些。
3·Explanation: Dramatic prominences can sometimes be seen looming just beyond the edge of the sun.
说明：生动的日珥有时候就会出现在太阳边缘外。
4·Just over the Sun's edges, several prominences are visible, while two prominences on the Sun's face are seen as light streaks just above and right of the image center.
刚刚在太阳的边缘，一些日珥是看得见的，而两个太阳的脸上突起为略高于和右图像的中心光条纹出现。
