RE: Need TLE for Falcon R/B

Adam,

 

The unidentified object was certainly bright this morning at 05:21GMT, observing from southern UK. The last time a Falcon9 2nd stage from a Starlink launch did not deorbit was in October 2020 on L1.12. It was two weeks after launch before Space-Track recorded any elements for the object (20070BS, 46669) and it seems to have come down a week later. I guess that remains the best explanation at the moment for the object from the L1.17 launch.

 

Regards

 

Richard

I don't think so it's Starlink-2211 

Take a look from TLEs from that days.

But this morning 8 March 2021 at 4:55 I saw this bright object in Coma Berenices. It has about -2 mag and Avery morning it's so bright. 

In simulation at this point of sky Starlink-2211 was earlier about 4:51

After this bright object I saw Starlink-2213 and then (40 deg to the west) Starlink train. 

Starlinks are very bright and separated at 100-120 deg. from West to East (they fly in Zenit).

The object flying ahead of the L1.17 train is Starlink-2211 which had failed to start orbit-raising when I checked yesterday. Because it is lower in height it is faster and hence flies ahead of the rest. The Falcon 2nd stage is deorbited on the second revolution. SL-2211 may be in a different attitude and hence appear brighter than the other spacecraft.

Hi guys.

Here in Poland we see great view on Starlink-20(L17) in the morning sky about 3:30 and 5:00 local time.
Before Starlink train fly bright Falcon second stage rocket.
I don't find any TLE for him. I'm asking why, that's big and bright object.

Can you help my with finding TLE ?

Adam, from Białystok, Poland
