Nico Thank you for the explanation. I got the fresh Tles from Celestrack today, but looks not correct. Regards

If you are still using yesterday's TLE set, then you will indeed find that BY70-1 is now about half a minute earlier. The problem is that the TLEs for this satellite are not stable yet in the first days after the launch. The right value for e.g. the decay rate has not yet been established. So for the time being you need to make sure you use the most recent TLE set that is available.
By the way, the two SuperView satellites are now using their own propulsion system to increase their altitude, preventing an early decay. As BY70-1 does not have any propulsion, it is stuck in its low orbit.
