Football shaped blinding white light in clear, sunny sky appearing and disappearing in high wind as slowly, steadily flying east.I was walking north on Tomahawk Trail between Moccasin Place and Ft. Lowell Rd., when I saw a blinding football-shaped light (that would be about the size of a 2-car garage were one up in the air) in the sky not more than three miles in front of me and roughly 1-2 miles in front (south) of the Catalina Mountains. It was flying below the altitude of the mountain top and moving very slowly from west to east. It then appeared to dissolve—just disappeared and then reappeared after about 3-5 seconds, again disappeared, reappeared after about 15 seconds (still very slowly moving west to east) then disappeared for good.The sky was perfectly clear and the sun shining brightly. Winds are VERY high here today and were averaging 22-26 mph at the time with gusts I’d estimate to be in in the 50 mph range. No plane I know of could fly that steadily and slowly in the winds blowing as I saw this. The light was way too large to be a balloon. Unfortunately, I forgot my phone and could not photograph it, but want to report it in case some one else saw it, too.
