左:

「1962 April 4, 5h 15m - 45m. / The first observation during this apparition. / Sky clear and free from clouds. The seeing / condition moderate, but the image unstable, /because of low altitude. L=241°. It is / near the time of appearance of the great yellow clouds in 1956. However, even the expected south polar cap was hardly detectable / owing to the image unstableness. 」

右:

「1962 April 11, 5h 40m. / The Sky was calm and clear. Surface markings in visible / due to the incessant distorsion of the disk. The sharpness / of the disk boundary improved rapidly with increasing / altitude of Mars, however after sunrise, the briteness / of the background sky abolished the image. / Ls=245°. Diameter=4.27". Ds=-22°, De=-24°. CM=34.5°. / After ephemeral calculation of the central meridian, / it was known that the darkness of the central part of / the disk may be identified with Margaritifer- Aurorae / Sinus.」
