32769Any new observations for artsat Spektr-R = 2011-037A?
- Jun 17, 2017Hello all,
If anyone has gotten astrometry on this object since 2017 May 3,
could I ask you to please copy the astrometry to me?
This is a radio-telescope satellite, launched in 2011 into a high,
very elliptical orbit, which has been occasionally imaged and reported
on NEOCP ever since then. Pseudo-MPEC, and some comments, are at
I just got an inquiry from a gent who plans to image this object
(wide-field photography) when it comes to perigee in early July; he
was wondering if the accuracy of the TLEs I've published for it, at
would be good enough.
I have a _lot_ of data for this object, ending on 2017 May 3.
Normally, I'd say there would be no problem finding the object. But
it's a (somewhat) active satellite. Because it's a big, light object,
non-gravs make it less predictable than it ought to be. On top of all
that, its uncertainty near perigee is a lot greater than at any other
time (because it's both closer and moving faster). So I'd feel better
if I had some more current astrometry.
Use of JSpOC (Space-Track) TLEs is out of the question; they've been
wrong by several degrees for years now. (I only compute TLEs for objects
JSpOC isn't getting right or isn't getting at all; for high-flyers such
as this, that's about half of them.)
Thanks! -- Bill
