i was outside doing yard work when i looked up to the sky and saw this "white speck" in the sky. i thought it was odd because it just that a speck like a hole in the blue sky. at first i thought it was a balloon. it was somewhat cloudy with winds heading north east. i observed it as it just hung there, so that theory was debunked. it wasn't a star it was as white as the cloud heading towards it, later that cloud obscured my line of sight (five minutes into observation). i ran into my house to get my camera hoping it'll still be there. as i waited for the cloud to pass i noticed it had gone. the thing that got my goat was that when i went on to finish my work a very high flying and fast plane passed right over the same area with a long contrail behind it. i was facing a little right over los angeles and it was high in the sky...i tried to focus my eyes on it . it was oval at first sight but as i focused it had a linear shape. shadows could be seen with angles. i hope other people had this same experience.
