Slow moving lower altitude substantial craft appearing to bend light around it

My girlfriend and I were on an evening walk up boucherie mountain in west Kelowna, Canada. Approximately halfway up there is a lookout spot which gave a great vantage point to the clear night sky. After admiring the stars for 10 or so minutes my girlfriend startled me by abruptly shouting out “what is that!?” And pointing into the night sky. After a brief moment my eyes came across what I can best describe as a bending of light, holding its form moving slowly across the sky at lower altitude. My uneducated guess would be maybe 10,000 ft in altitude, significantly lower than a civilian aircraft. We could not make out any details of any alien/military craft. Light appeared to be bending around an unseen object shaped almost as a chevron, but with a straight edged horizontal nose. The light bent/refracted around it was almost identical in hue to the particularly colourful deep tangerine moon. My girlfriend described the effect as looking like a “forcefield.” The craft/object moved in linear direction and speed, slowly moving across the night sky until travelling too far away to be seen. It did not leave behind any contrail. The size of said anomaly was maybe twice larger than the size of the Little Dipper, also present in the night sky. The lighting bent around it perfectly held its form, traversing a massive portion of the sky until travelling out of view.
