Seemed to be cloaked-no lights, no sound, simply movement in sky, it glided by heading SE.

This is the second time I have seen one of these. The first instance was in November or December of 2022, this second instance was May 2 at 1:59 AM. Both instances, I was outside viewing the stars, and noticed movement out of the corner of my eye, so I focus on that spot. Definitely a chevron shape, although it is difficult to explain, as they appear to be made to blend into the sky. Absolutely no sound or lights, they simply glide by. The whole experience only lasts for seconds because once they glide by, they just kind of blend into the night sky. It would be impossible for me to get a picture due to how well they blend into the surrounding area. I am a 66 year old, retired female. I used to be a programmer as well as a system administrator for retail corporate offices.
