Infrared images of the lunar eclipse of 13 April 1968 were obtained and compared with infrared images of the 19 December 1964 eclipse. A similarity of apparent strength and distribution of most thermal anomalies on the maria is evident from inspection of these images, indicating that these features are not ephemeral. One new linear thermal anomaly was discovered, which is thermally enhanced during the lunar afternoon. Its close relation to a lunar crustal fracture line and other features of probable internal origin suggests that this anomaly may be of internal origin.
获取了 1968 年 4 月 13 日月食的红外图像，并将其与 1964 年 12 月 19 日月食的红外图像进行了比较。通过检查这些图像，可以明显看出玛丽亚上大多数热异常的明显强度和分布相似，表明这些特征不是短暂的。发现了一个新的线性热异常，它在月球下午时热增强。它与月球地壳断裂线的密切关系以及其他可能的内部起源特征表明，该异常可能具有内部起源。
