Never been to the Pacific Northwest myself so I can't match your sighting, but I'm curious about the shape and movement you described. Was it doing that stop-start thing a lot of craft reports mention, where it just holds position and then shoots off with no acceleration curve? That detail always stands out to me.
Also wondering if you logged it anywhere official like MUFON or even just wrote down the exact time and coordinates while it was fresh. Those details matter more than people think when you're trying to cross-reference with other reports from the same window.
Anyone else on here from that region? Would be good to know if theres a cluster of sightings from around that time because March is coming up a fair bit in reports I've been reading lately and I don't think thats coincidence.
