[amsat-bb] ISS "running late"

[Corey Shields]

About a week ago it was found
<https://community.libre.space/t/tle-issue-satellite-with-old-tles-2020-11-09/6935>,
as acknowledged on space-track.org, that TLE updates had stopped for a
number of days. Given that this is the core source for most TLE feeds
today, a disruption is to be expected, but we found their feeds had
recovered around Nov 11.

Celestrak and calpoly are both up to date on ISS. AMSAT is the only source
I am aware of associated with nasabare.txt so I will assume that is where
you are pulling from, and the ISS element in that file is definitely behind
(as of this email). I don't know how this file is updated - the delay could
either be coincidental or maybe the upstream issue from a week back has
wedged something in the process?

So, you are right about the orbital adjustments in times like this, but you
are also correct that the TLE is behind as well.

Cheers,
