These events of July 3 represent the primary sightings during the encounters at Antartica during the summer of 1965.
The site of this observation was the Argentinian base on Laurie Island in the South Orkney Islands. At 17:03 hrs. on Saturday July 3, 1965, two meteorolgists, Jose Jarriek and Jose Mazzuchelli, observed for 15 seconds a round bluish-white object moving east to west on a parabolic path. Its size was bigger than a first magnitude star. Two variometers (instruments that monitor the local magnetic field) registered sudden and strong disturbances of the magnetic field which were recorded on their tapes at the time of the incident (17:03).
The same day,' Saturday July 3, 1965 at 19:20 hrs, nine garrison members of the Chilean base (Pedro Aquirre Cerda) observed for 20 minutes the maneuvers of a luminous object of solid appearance and yellowish-red color which occasionally changed to green, yellow and orange. It moved at high speed, mostly in a straight line with oscillations, but it also hovered momentarily. A wake, apparently steam, followed its passage. It was initially observed toward the north at 40 degrees above the horizon, and finally disappeared in the clouds toward the S¥ at an altitude of 45 degrees (Figure 5). The night was clear and starry, with a waning moon, 2/8 coverage of strato-cumulus and a few cirrus; the wind was of the order of 80 Km/hr (50 miles/hr) (*) f The witnesses were performing routine meteorological observations.
This sighting took place at the Argentinian post just two minutes after the termination of the previous observation at the Chilean base. It lasted 62 minutes, from 19:42 to 20:44, and was witnessed at different moments by a total of 17 persons (14 members of the Argentinian garrison and three visiting Chilean sub-officers). The UFO was described as a circular object of solid appearance with a red center and ill defined edges of changing colors (yellow, green, orange, blue and white). It was moving in a. zigzag trajectory from right to left with respect to the witnesses, appearing initially toward the NNV.with 30-35 degrees altitude. Its maneuvers at low speed included hovering, accelerations, reversals of direction and luminosity changes. It was hidden at times behind the clouds (stratus), but it was also noticed in front of the cirrus backdrop. It finally disappeared toward the NW, decreasing in size and gaining altitude. The distance between object and observers was estimated first as 10-15 Km (6.2-9.3 miles) and later on as 20-30 Km (12.4-18.6miles) . The. UFO was first noticed by Sub-Officer Aldo Irusta who was at the meteorological observatory of the post. -The weather conditions during the sighting were totally similar to those of the sixth observation.
(*) One must recall that July at the South Pole is midwinter when the bases are totally cut off from the rest of the world.
