    Thanks very much, Ted, for these search TLEs.  Unfortunately there's a
    frontal system over England at present so I'm unlikely to get an
    opportunity to observe tonight although I will be monitoring satellite
    imagery in the hope of a cloud break arising.
    
    I observed two unidentified 'Molniya' objects last year over short arcs
    which were never identified.  It occurs to me that last night's object
    may match one or both of those.  Is it feasible to check those obs out
    on the off chance that they match?   I regret not having the ability to
    perform such a task myself.  For convenience I'll repeat them here:
