At the start of this monitoring period AO-73 continued to perform in an unstable spin attitude with AO-73 rotating about the Z-Z axis but with a variable rotation about AO-73’s offset Centre of Mass. As noted last week AO-73 the rotation period about the Centre of Mass had been noted to be in the range, 450 to 600 seconds.
On the 12th July the motion about the Centre of Mass “consolidated” as AO-73’s rotation about the Z-Z axis.
