And when we know this, re-entry window, wouldn't it be neat if someone could catch it on video coming back in?

18:20 pass not as strong as prior passes. Only got a few moments of full-quieting audio. Contacts with W5ACM and KC7M. As before, the second half of the pass was much better (nothing heard at all until just before indicated TCA), so perhaps the bird is late compared to the Keps. Worked it almost into the ground before LOS. I'm using 2016-083C, updated from Celestrak right before the pass. Playing with polarization seemed to help, but I'm assuming the bird's antennas are linear, right? Possibly my relays are getting dirty.
One question, for scale... We know that the satellite will not last "long", given it's crippled orbit. How long? Days? Weeks? Months?

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.

Hi We had a low pass over here minutes ago and i felt the keps BY70-1 are wrong . I start to hear 25 seconds before . Does anyone feels the same ? 73 _______________________________________________ Sent via AMSAT-BB@amsat.org.
