Hiking in Carbon Canyon--out taking pictures Sunday, March 6th 11AM--snapping pictures of clear, beautiful blue sky and puffy very-white clouds after previous night's rain. Took 71 pictures. Hours later, when sharing pictures, noticed light blue circle, different blue than sky, in 2 pictures. Upon further review of pictures, a light-blue sphere or circle was able to clearly be seen--with 4 prominent white lights. The object was not noticed or seen while I was taking the pictures at time of hike. In reviewing pictures that were snapped in quick succession, millisecond rate of frames, the circle appeared to have moved from a cloud to open blue space between clouds--when I look at the pictures taken this is very evident. Images clearly show object--1st picture is object from distance--original photo--second picture is zoom of that picture, 3rd picture clearly shows circle with lights and is isolation and further zoom of object, 4th picture shows sky with no object. Object is not seen in pictures taken immediately before and after pictures uploaded. Many pictures taken in this area over years--this is 1st with anything like this in it. The area is also in flight path of planes--commercial and private--going into LAX, SNA and Ontario to a degree. Many planes fly over area, one after another constantly. While hiking in same area yesterday, planes coming from south appeared to be flying unusually low and doing circular patterns thru clouds in early evening.
