2020-06-26 - Wellington, CO - Triangle

Seen a UFO from car window between Fort Collins and Wellington, Colorado, on 06/26/2020, traveling south as i was traveling north, got to watch it for 2 min from distance of 2 miles high and for approximately 5 miles of flight.  It was 8:30 pm, wicked rain storm east, above me it was grey clouds to west another storm with lightening and sheets of rain.  There was sun light, it was not dark out. Lightening struck behind it and i watched it slightly darker then its surroundings (storm was moving east, it moving south- this caught my attention). Once I zeroed in on it, I could see it plainly.  I could see through it(mountains behind it) but the outline of vessel was clearly visible, triangular in shape, middle more translucent then outside with 3 circles on each  corner, no lights on. It moved close to me and i could tell size was the same size as a cessna used to crop dust in this area at about same height which is lower then other planes.  It moved smoothly an! d quickly out of sight just above tree line.
