Well i never tryed to compute the size of it but it had to be huge compared to the clouds it was movin behind.!!!
The sky was almos filled wit big white puffy clouds an the only part of the ufo i saw was behind the clouds as in the gif.!!!
In my gif the movment is "jerky" but the actual movment i saw was smooth but moved at about the speed it apears to be movin in the gif.!!!
The oldest girl hollered "LOOK"... an me an the other girl looked whare she was pontin an she screamed an then me an the oldest girl instently screamed as we all 3 immediatly ran to the house... so i only saw the ufo for about 3 seconds.!!!
