Note that it will be too far north at closest approach for viewing from Australia. It will be visible between midnight and morning on Oct 31, however it will be about mag 13 shading to mag 12.5. That will make it a tough visual target, especially as the Moon is only about 20 degrees away. I've observed NEOs visually at around mag 10-11 with an 8-inch telescope. Larger instruments will be necessary for this one. Video imaging with a large instrument might be the go.
