UFO Sighting in Port Alberni, British Columbia on 2017-07-30 23:10:00 - Bright light, sphere, zig zagging but straight line,no sound,no flashing lights, faster then a plane

Time 11:10 pm, outside with dog, i was looking to the west and saw what i thought was a bright star, then noticed it was moving. i watched it for a few seconds and it was almost vibrating/zig zagging but still going in a straight line if that makes sense... it was then i called my husband and he came out and watched it also. it continued to move west to east, no trail after it and absolutely no sound as i waited to hear any but none came. there was no flashing light as an airplane, it was a bright white light. i watched as it for approximately 1-2 minutes as it went to the east staying at the same elevation the whole way until it disappeared from sight.
