Re: Eirsat1 launch Friday 1st Dec from Florida space x
Locations from which decoded beacons have so far been received in the first pass include Donegal, Slovakia, Czechia and Luxembourg
I don't have any accurate TLE

On the first pass over Europe EIRSAT 1 was almost 10 minutes late on that preliminary TLE set and almost 4 minutes early on my TLE set. Let's see if we can find better parameters.
Since this is a classified launch, TLEs may not be published by the usual sources, so we may have to determine those ourselves.

Graham,
Note that both TLE sets, whatever their source, are now obsolete because they refer to the originally planned launch date of 2023-11-29. Since the launch is now planned for 2023-12-01 at 18:18 UTC, that TLE set should be changed to:

Some initial TLEs have already been published. Since the separation between satellites in the first cluster is very small, you can use any TLE in that cluster for EIRSAT 1 for now, e.g. the TLE for object 58472.
