We saw 3 lights in the night sky in the shape of a triangle that slowly faded away without moving.

We had been interested in the night sky for some time before this and had been taking walks at night to see the stars and planets. We had gotten used to the late-night sky and wanted to see how much the sky had changed overnight. So, we woke up early one morning and took a walk before the sun came up. At the corner of Muir Drive and Newvale Drive, where we could see the sky clearest, by chance we spotted the ISS making a pass over us. That was confirmed by a satellite tracking app we had. Not two minutes later, looking to the northwest, I spotted three lights in a perfect equilateral triangle shape in that direction I had not seen before. Initially I thought they were stars I missed, but the person I was with said there was nothing in that direction before the ISS passed over. The triangle was just over the mountains, but it was too dark for me to be able to determine the distance. Also due to the darkness, I am unsure whether it was three separate objects or one whole object. Of the three lights, the highest light had an orange color, as did the lower right light. The lower left light seemed to be somewhat larger than the two others and was not orange, but a bright white. The lights did not move at all or make any noise. None of them flashed or changed color. The ISS passed over at exactly 5:50 AM and the lights were not there before, putting the object’s appearance sometime between 5:51 and 5:52. By the next minute they had completely faded away. It was a completely clear morning, no clouds and very little wind.
