VISUAL PHENOMENA - SIGHTED FROM 'TAYLOR' 1958

On July 17, 1958, four individuals—P. Trost, G. Knuckey, P. Chapman, and I. Adams—observed an unusual visual phenomenon while standing at sea level near the Taylor Glacier in Antarctica. The event occurred at approximately 1300 hours (GMT+7) during a period of bright, rosy twilight, with the sun not yet above the horizon. The sky was largely clear, save for sparse high-level clouds. The display lasted for 20 minutes and consisted of two distinct forms that moved from the eastern sector toward the north. The first form was described as an indefinable blob of shadow traveling from right to left at a speed comparable to auroral movement, with shadows appearing at regular intervals of approximately three seconds. The second form consisted of a group of parallel rays, also moving from right to left, which resembled auroral drapery but were noted as being more regular. These rays were described as having a brilliancy approximating a strength-one aurora and were white in color, contrasting with the surrounding pinkish sky. The rays extended from the horizon to an elevation of 10 to 15 degrees before blending into the sky. The observers noted that the rays were inclined at varying angles depending on their position in the eastern or northern sectors. The report concludes with a note of regret that the observers were not equipped with instruments to obtain precise measurements, meaning the data provided is based solely on the observations of experienced personnel.
