As Russell pointed out Mike is depends on observations of this
satellite to produce
the classfied TLE, as they are not published by Space-Track.
Your mail with the video will help to fine tune the TLE, so it can be
observed by
others and we don`t ´loose´ this sat.

I have observed Helios 1A this year on Jan 01 and 17; Feb 16 and 22.
It was steady in the first 3 obs; in the 4th S in the first image and
fading to invisible
in the 2nd image.

This what I reported Jan 01 when I imaged it as an UNID.
Unid imaged:
