2015-08-06 - Rochester, MN - Triangle

3 orange lights, forming a perfect triangle in the SW sky, without sound or motion.

I witnessed 3 glowing orange to red orange orbs to the SW. The 3 objects appeared to be independent of each other and oscillated at different intervals. I could not discern the presence of an overlaying craft (these did not appear to be lights attached to a craft of any kind).

The 3 orbs began as a single light and progressed in short fashion (maybe 10 minutes) in to 3, presented to me in the form of a perfect triangle in the sky. I did not see any apparent motion nor did I detect any sound resonating from the SW.

I initially had thought that the single orb was a forthcoming helicopter (mayo one does fly in this area) however, after seeing no motion and then witnessing the 3 in the sky, forming a perfect triangle, I knew that this was something completely different.

I'm not sure what I witnessed but the fact that it maintained a perfectly triangular shape and quickly disappeared, after 30 minutes had elapsed, left quite a lasting impression in my mind.
