Tuesday may 30, 2017 around 10:30pm at about the city of temple city or arcadia california or maybe slightly more towards the north, a dim light above the clouds was seen by my children and me. this evening we had a overcast night that started around 6pm or so, curiously i began seeing planes at high altitudes during the afternoon passing by and leaving chem trails on our nice clear day, but not sure if that's what created the current cloudy evening. from my point of view standing south of the 10fwy and about san gabriel blvd. i saw the dim light above the overcast sky, looking north slightly east (or also) pointing north at around 2 o'clock. like i said we had a overcast night and the light was above the clouds but looked more like a big light (something like a round shape) at my distance could probably say it looked like aircraft that was hovering for long time, but not to the effect of shopper, just a brighter part of the sky that looked very odd. as i invited my kids to view the (what i called a ufo experience) bright part of the sky, they said it looked weird as well. the brighter part of the sky was maybe lit around (by my guess) 50-75ft and obviously created and effect of a dimmer glow around it extending it to maybe around 100ft in diameter. the lit part of the sky was stationery and also seemed to have a sort of trail going east to west. i saw this for a good few minutes before i called my kids to come out and see it, after a a short while we decided to go back in. according to the weather reports: 67.2℉ overcast 1500ft wind 1mph visibility 9 miles dew point 57℉ humidity 81% moon=waxing crescent
