I'm an airline pilot. Taking off from Kansas City January 5, flight number 4030 at 6am. Around 30000 feet we noticed a hovering object to our east. It was at least 2 times our altitude, and much much larger than an aircraft. It was pulsating white then red and then a short green in a rhytic pattern. It's path never changed but it rose higher and higher in the sky until you could only see the white light. It was brighter than any other star in the sky and once the sun rose no stars could be seen but this was still there. I took a picture with my iPhone and when zoomed in it appears to have a square shape with brighter lights on top than bottom.
