我们目前的高分辨率图像的太阳在近紫外线光谱范围内的214纳米和397纳米之间的1米日出气球载太阳望远镜的第一次科学飞行获得。在此波长范围内发现的安静太阳均方根强度对比度是安静太阳太阳表面结构中获得的最高值之一，在214 nm波长处高达32.8%。我们比较均方根对比从观测数据与理论强度对比从数值磁流体动力学模拟。对于388 nm和312 nm，观测结果与数值模拟吻合得很好，而在较短的波长下，观测结果与模拟结果之间的差异仍然存在。
We present high-resolution images of the Sun in the near-ultraviolet spectral range between 214 nm and 397 nm as obtained from the first science flight of the 1 m Sunrise balloon-borne solar telescope. The quiet-Sun rms intensity contrasts found in this wavelength range are among the highest values ever obtained for quiet-Sun solar surface structures—up to 32.8% at a wavelength of 214 nm. We compare the rms contrasts obtained from the observational data with theoretical intensity contrasts obtained from numerical magnetohydrodynamic simulations. For 388 nm and 312 nm the observations agree well with the numerical simulations whereas at shorter wavelengths discrepancies between observed and simulated contrasts remain.
