A UFO was sighted by people in scattered locations around the San Francisco Bay area.
A particularly detailed report was obtained from officer Galen Anderson of the Sunnyvale Police Department, who observed the UFO for about 45 seconds.
About 4:20 a.m., Officer Anderson was patrolling the streets in a squad car. A radio call from other officers alerted him, and he stopped to watch the UFO. The object was traveling from east to west at an elevation angle of about 45°, at about the speed of a propeller driven aircraft. The leading edge was brightly illuminated, the main body grayish in color, with a small point of light visible on it.
The UFO then made a turn toward the northwest, was momentarily visible edge on, then quickly disappeared from view.
In nearby Monta Vista about 4:15 a.m., George W. Scott was on the job as a supervisor at the Permanente Cement Company. One of the work crew called his attention to a strange object in the sky, and he watched its flight for about a minute. To him, it appeared that the UFO stopped briefly each time the small body light pulsed, then moved 3° to 4° between pulses. The UFO continued on a westerly course, disappearing behind the coastal mountains.
This object appeared larger than a full moon, according to Officer Anderson, about basketball size at about 8' away.
It appeared as a disk on edge, with about ¾ or more of its outline showing. The trailing ¼ of the circle, if it were there, appeared more or less invisible. Police Officer Lt. Haag told Anderson that he saw what appeared as heat waves in this quarter area and further to the rear. The disk appeared grayish in color except when the small spot of light lighted up about every 3 to 4 seconds. The color then changed to yellowish/white, some trace of orange, but predominately along the front leading edge portion.
This produced a pulsing effect every 3 or 4 seconds. This, in turn. gave an eerie lighted haze or mist illumination of the area just outside the disk circle itself as if it were glowing or surrounded by a gas, or thin cloud, halo, etc. At each 3 or 4 second pulse, the small inner bright light would move around erratically to various new positions within the disc area.
The object was visible about 45 seconds to Officer Anderson and traveled in a perfectly straight line over Sunnyvale toward Los Altos, then suddenly made a turn and was momentarily edgewise and vertical to Anderson’s vision, then immediately disappeared from sight. Officer Anderson and Lt. Haag were only about a third of a mile apart at the time and Officer Girard was perhaps a mile to their northeast. Speed of the object was about that of a propeller driven military aircraft, elevation about 45° from Officer Anderson, estimated altitude 4000' to 6000', visible about 45 seconds. Brighter than full moon.
