At 11:04 pm on july 20th we were standing in our yard waiting for a predicted comet. right when we got outside, we noticed a light pulsating above our neighbors tree. we thought it was a satellite, but it started to move up and to the left. it then immediately did a sharp right and continued on a straight line for a minute. it was above our tree and it started to veer right and go behind the tree. so we ran to the other side of the tree and it was gone. the object itself was probably farther away than the iss, but the time between its flashes varied by a couple seconds. it varied between really bright and dim flashes. it was also moving very fast, probably faster than all the satellites iâ€™ve seen. there was no pattern to the bright and dull flashes. the light color was white. we are sorry there is no photographical evidence as it was too dark for our phone camera to pick up anything.
