A set of very bright lights: one green, one red, and one white, close together, kind of pulsating in the night sky overhead. brighter than stars. no sound. moving a little perhaps, but slowly, northeast to southwest. i pulled out my 600 mm lens and zoomed in on it and took the attached photos, assuming the focus would be bad, due to the distance and night time conditions, but thinking it would maybe help me see it better. the photo revealed 3 lights at the corners of what appears to be a triangular structure/craft. way too high up to be a drone. again, no sound. i don't have a strong opinion about what it is. i'd like help analyzing it. second photo (lower quality, sorry) was taken about one minute after the first, showing that the lights had shifted, appearing to have rotated.
