Over the last week AO-73 has continued to spin, reverse to what we know as the normal direction. In recent days increased Nutation has developed.
Based on past observations we should expect AO-73 to commence tumbling in coming days.
This may or may not result in AO-73 returning to its normal spin sequence.
