Usual this day was the fact that yellow light was more intense than any other color. Yellow also peaked an hour before the other colors of the spectrum. At 4:30, yellow began to dip in intensity relative to the other colors.
Red light generated two intensity spikes again, one over three hours prior to local noon and another at three hours after local noon.
