Hi All

Thanks for the interest off list.

We have been offered the following TLE by a team supportive of amateur 
observers that was derived from optical observations, which should help 
considerably for observers with narrow field instruments compared to 
Spacetrack TLEs derived from various sources.

1 26113U 00017A   18024.17522569 0.00000000  00000-0  00000-0 0    07
2 26113  93.9688 259.8169 7375521 279.0884 335.6339  1.68677684    01

The elements can be attributed to the collective work of ASPOS OKP and ISON. ASPOS OKP is a system developed and managed by Roscosmos.

Another area of potential interest would be RF data collection of the +/- 1.7MHz data side bands of the spacecraft's down link.  Gaining an understanding of the stability of this signal maybe helpful to any recovery effort.  The down link is centered on approximately 2272.505MHz.

I'm clouded out so unable to contribute optical observations for at least the next few days.

Thank-you for the support.
