this is a summary of observations i made of an extremely large and extraordinarily bright object (-4> magnitude) that i videoed for three minutes, beginning at 5:00 am est, on june 4, 2019. in that time, the object crossed appropriately 40 degrees of sky and flashed in a patterned, periodic rate; paused for twenty-nine (29) seconds, then started a distinct, second periodic flash pattern. i copied forty-nine (49) images from the total 3:01 minutes of video1. the images are of an object that had an apparent size of 100-200 meters (.10-.20 degrees of arc in size2) and had a generally rectangular shape. to the unaided eye the object resembled a large solar sail, mylar gold in color and rotating counter clockwise3. none of the images shows what might be considered control surfaces or a means of propulsion. no aircraft were in the area at the time of the recording and no aircraft noise can be heard on the video4. the weather was clear with only a few cirrus clouds. visibility was beyond five (5) miles. i used adobe premium rush software to isolate, copy and time index each of the forty-nine (49) frames where the object appears in the video. when i entered the flashes on a timeline they produce two distinct patterns separated by an appropriately twenty-nine (29) second break in activity. the pattern is formed by the time periods between the flashes, similar to a lighthouse. the first two flashes that occur are separated by a period of 3.60 seconds. the next flash in the sequence occurs 10.77 seconds later. 10.77 seconds is divisible three times by 3.60 seconds. all other flash periods in either sequence are also divisible by 3.60 seconds, to no greater than .01% difference. letting 3.60 seconds = the value 1, the first set of flashes form a patterned ratio of 1:3:1:3:1:3:1:3:1:3:2:1, expressed in 3.60 second units of time. at the end of the first set of flashes there is a 28.97 seconds break in activity and then a different pattern picks up with the ratio changing to 4:3:1:4:3:1; until the end of the video. there is also an extremely large change in luminosity between flashes with a pattern change that seems independent of the flash patterns, themselves. during the first pattern of flashes, the luminosity alternates between a lower and higher intensity light at each flash so, low, high, low, high; until the pattern ends. in the second pattern, the flashes follow a low, high, high, low, high, high; intensity pattern. i would estimate the low intensity flashes near 1-2 magnitude and the higher intensity flashes at above -4 magnitude. if the flashes were caused by the predawn sun the object would have needed to be at a minimum altitude of eighty (80) miles5. i have a b.S. in industrial science, i'm a former bomb tech, and a 100% disabled vet. my most recent work has been as a professional legal advocate and representative in federal administrative court. i have flown fighter-trainer aircraft, i'm an amateur astronomer, a space buff, mensa member, and i'm currently retired. please contact me with any questions and please let me know your impressions. sincerely, /s/ david a. greenidge david a. greenidge 5330 passion fish lane grant, fl 32949 [email protected] (321) 427-2389 mobile iphone 6s, panned fully out to the 73 degree field of view limit of the phone. as it changed position the object appeared to double in apparent size over the time of the recording. see attached print images. the video doesn't reflect the rotation. i was able to still see the object in between the recorded flashes. for comparison, i've included a short video of a small aircraft that i took with the same iphone and standing in the same location, predawn. dawn was at 6:26am est on 6/4/2019, and the object was recorded at 5:01am est.
