Hallo Peter

Ja, Buccaneer und Mirata wurden kürzlich getauscht. Habe um 23.10
folgendes Mail erhalten:

> Due to Thanksgiving being on Thursday, the AMSAT-NA TLE Distribution for this 
> week will be today, November 21, 2017. Next week we will continue with the 
> normal TLE distribution on each Thursday of the week. Note that, per comments 
> below, AO-91 is most likely object 43016.
>
> It appears that AO-91 is in the group of cubesats launched on 11-18-17 that 
> include objects 43016, 43017, and 43018. The object 43015 that we were using 
> for AO-91 has separated enough to be confirmed as Buccaneer RRM by 18th Space 
> Control Squadron at Vandenburg AFB, CA. One of 18 SPCS many missions is launch 
> analysis.
