Apologies for the Swedish text above !

I had initial troubles yesterday predicting the decaying Long March rocket
I suspected,
The current elset on Heavens-Above showed no future (or previous !) passes.
It had a strange object name, but I saw nothing else that looked suspicious.
Also the latest five elsets from SpaceTrack this morning showed nothing in
HeavenSat !

But late afternoon here I got good H-A predictions, and you may have a
chance to see it before decay !

Your pass was from NW, culminating 09:58:14 UT Dec.29 at  81° in the NE and
204 km altitude !
