极光弧的最大光度高度是根据一般极光活动之夜（1959 年 11 月 27 日至 28 日）期间美国西部三个观测站的同时观测估算得出的。在光度学上，该弧的特征是 [O I] 6300 A 线的选择性增强。根据 24 次单独测量，高度为 412 公里，一次观测的标准偏差为 ±23 公里，平均值为 ±5 公里。讨论了弧线的地理位置、方向及其在夜间的运动。
The height of maximum luminosity of an auroral arc is estimated from simultaneous observations at three stations in western United States during a night of general auroral activity (November 27–28, 1959). Photometrically this arc is characterized by a selective enhancement of the [O I] 6300 A line. From twenty-four individual measurements the height is found to be 412 km with a standard deviation of ±23 km for one observation and ±5 km for the mean. The geographical position of the arc, its orientation, and its movement during the night are discussed.
