While i was home alone working outdoors on my farm august 9, 2018, i placed my cell phone on a plastic chair in the front yard. i was unaware until today, august 15, 2018, that photographs had been taken approximately every 6 seconds for 30 minutes beginning at 1400 and ending at 1430. as i discovered nearly 300 photographs on my phone today, i was stunned, as i had not taken any of them. at first glance, i thought all the photographs were identical: the white chair, the insect repellent, the leaves on the tree. after enlarging a photo, i discovered that there was a bright object in the sky above the clouds. after looking at each photo it is clear that the object was hovering in place yet changing its orientation while at the same time becoming brighter and at times appearing to be several separate objects. according to my cell phone, the object remained hovering for 23 minutes. at the time, i had no awareness of the object and no knowledge of my cell phone being in operation. i discovered the photos and object while at work today and am quite shaken. i am anxious to share the photos, to get an idea of what the object was and receive an explanation for how my phone was able to take a photo of the object every 6 seconds or so for 23 minutes with no human intervention. i did not notice anything else abnormal about that day. i have not downloaded the photos to my computer yet. i am hoping that i can add them as an addendum to this report at a later time.
