2022-03-09 - Harwinton, CT - Triangle

Massive black triangle with curve corners, a red, yellowish, and blue round set of lights under each side hovering overhead

It was dark and I turned on our garage light. As I walked down back stairs to our driveway, I heard a low but deep sound. When I reached the driveway, I looked up and right above my head was a massive black triangle that also extended past our ranch home and just above our roof. There were
A set of red, blue and yellowish round lights underneath each side. Since it was dark out and the craft was black, I believe I was only able to see it because of the lights underneath it and being underneath it as well. They were not blinding, so I could see the entire shape of the craft which hovered over and then very very slowly moved completely over roof then gone in seconds. I watched it for a good 2 1/2 to 3 minutes at most I’d say.
Needless to say I was in awe.
I am a 66 year old wife, mother and grandmother. I decided to find where to report, since I’ve been unable to get a full nights sleep since the encounter-not through fear but the unbelievable experience I was lucky enough to have.
