17 Sep 2022 = 2.73 seconds (from the Sun Sensor Data)
18 Sep 2022 = 2.78 seconds (from the Sun Sensor Data)
19 Sep 2022 = 2.78 seconds (from the Sun Sensor Data)
20 Sep 2022 = 2.78 seconds (from the Sun Sensor Data)

AO-73 continues spinning about the Z-Z axis at a fast rate with the Z-Z axis very slowly precessing about AO-73’s centre of mass in a relatively stable attitude.
Over the last two months 22 July to 22 September AO-73’s rotational spin has slowly decreased from 27 rpm to 21 rpm.
