Current Space-Track elements seem to show this bottoming out at 138 km altitude at about 15°N, 108°W at 23:43 UT this evening, shortly before making a southerly pass at my 20 (Toronto, 43°N 79°W). Is a perigee of 138 km terminally low?

It is the rocket body from the latest Progress mission just docked, so presumably could be described as a Soyuz R/B.and of course has a 51.6 degree elevation. There is an illuminated dawn pass in shortly at 1843Z and conditions here are good but with some adjacent cloud which may spread (hoping not!) Unfortunately this may be too short notice for NZ observers, apologies that I was not convenient to post anything earlier. One of the most likely daylight near decay passes is currently predicted at 2318Z which is too low for me to observe owing to hills but should be favourable for the South Island. The next pass if still in orbit is about 0051Z and is predicted around 40 degrees elevation , conveniently at a time when observers may be able to see it in their lunchbreak from work in New Zealand :-) Earlier daylight passes are at 2014 and 2147, the latter too low here but definitely worth checking on in the South (refer SpaceTrack for more into.) The above of course assumes an uncontrolled re-entry but even if controlled decay in the South Pacific would seem to be a possibility.
