Mark,

Space-Track has a prediction for today, but not more specific. They seldom issue a final report of CubeSats though they will stop issuing new Keps. So, we need to use inference. Given the weak beacon, that is even trickier.

Using the latest Keps, it should reenter around now, but with a wide range of time. One strong indicator is from the Status Page. EA6TA has regularly been reporting it was heard for the past few days. Today around 1430 UTC, he reported it was not heard. So it is likely down, or at the very least rendered inoperative by heat. Watch that page, just in case.

73,

Alan WA4SCA

Well, given that the last active report on that list is five days ago, I'd say that people aren't using it.
