Watched the ISS, Proton rb and Nauka on a morning twilight pass in the 
SW from Coonabarabran (-31.30S, 149.16E) between 20:06-20:16UT.

At 20:12UT, the Proton rb trailed the ISS by 3m32s and Nauka trailed the 
ISS by 4m02s.

All were steady brightness in the SW:

ISS     mag -1.5
Proton rb   +1
Nauka   mag  0

until the Proton rb  got very low in the south where it displayed smooth 
brightness variations of around 2 mag. I timed four consecutive minima 
and the three intervening maxima, giving a peak to peak of 10.4 +/- 
1sec. The mid of the three maxima was at 20:14:37UT.

Cheers, Rob
