At 4:05am today, june 15, 2020, i witnessed a light in the sky, about 2 degrees east of due south from my location. it was not there a couple of minutes earlier. it looked similar to a jet trail at first, but luminous. it became brighter and consisted of a straight line of light, slightly widening as it rose in the sky, with individual brighter spots moving upward slowly within the band of light. as it rose, the tail, which was near the horizon initially, rose as well, and i realized it would be above the line of sight from my window in a minute or so. i got my cellphone and went outside. it had vanished in the 30 seconds or so it took me to get outside. the whole episode was over by 4:08am. very vivid. my only sighting of such a thing. i am 69 years old.
